Advice Dwarf Breeding Behavior?

Enable HLS to view with audio, or disable this notification

15 Upvotes

Hi! I noticed some odd behavior from one of my rasboras today, where it seems to be chasing another around. It also suddenly had a slightly darker coloration. I didn't know if it was stress related (just added a couple shrimp and did some gravel cleanup), so I dimmed the lights. I do have 4 fry in my tank so I know they're breeding, but I'm not sure if this is related. Are they fighting? My other rasboras seem normal. Any info is appreciated!

10 gallon / 1 chill betta / 2 Amano shrimp / 7 adult rasboras

Parameters:

Ammonia 0/Nitrates 5 ppm/Nitrites 0

Kept between 78-80F

Lots of live plants

Sponge filter

Gravel cleaned every 2-3 days, small water change every week

I think they are Strawberry Rasbora, but I am not sure. The first one looks like male and the other looks similar but not so vibrant. Ignore the shrimp and the chilli rasbora in the background.

Illness Small white growth on Pygmy rasbora - plz help

Thumbnail

13 Upvotes

I just found this small white growth on one of my Pygmy rasboras right next to the black dot in the middle. Iโ€™m not sure if itโ€™s bacterial or fungal, and I checked parameters and had 0 ammonia, 0 nitrites, 0 nitrates (tank is fully cycled and is heavily planted). The 7 other rasboras with him all look normal and act fine, including this one as heโ€™s still eating and being active. I had an endler who had something similar to this on his face and I got rid of it using a salt dip, but he eventually randomly died a couple months later. Is there anything I can/should do about this? I donโ€™t have a quarantine tank, and Iโ€™m worried about dosing the whole tank with medicine.

Thank you

Advice Micro rasbora and flow

Enable HLS to view with audio, or disable this notification

57 Upvotes

I just changed the flow in my tank so thereโ€™s a current across the top and front of the tank. The middle seems to be calm. My strawberrys and maculata are being kind of nuts about it, they gather and swim into the current and get all tossed about. Do I need to worry - is it a sign of stress? - or are they just playing? They can easily get out of the flow if they want.

Strawberry Rasbora Recently moved strawberries have white/silver spots

Google says it may be normal if its not fuzzy etc. but I wanted to make sure. I recently posted another post here asking about their behavior, and I moved them to a planted shrimp tank I have. I noticed that some of them have white/silver spots now. Is this because theyโ€™re stressed due to the move, or could it be the ick?

Edit: Fixed spellings

Identification Is this a chili rasbora? I got some cherry shrimp today and this tiny little thing was in with them. I was wanting to get ember tetras but Iโ€™m really loving him more. The only thing is nobody has any of these little guys in stock. Are they hard to keep alive? Iโ€™ve heard they die easily

So I was trying to get into breeding strawberry rasboras and I was able to do it I have 5 babies in this automatic egg catcher I need help in what to feed them I had 3 jars ready to grow infusoria for the babies but all my jars keep dying I canโ€™t grow infusoria itโ€™s either too hot, too much ammonia not enough plant matter or whatever else itโ€™s not working, for now I have these fish in the nursery with sphagnum moss and guava leaves to grow biofilm and feed the smaller insects inside like daphnia, seed shrimp, detritus worms, black worms, and copepods, I feed hikari first bite and microworms because I have no clue what else I could feed them if infusoria wonโ€™t form.

hi everyone!

i have sand in my planted tank and have noticed during feeding time my strawberry rasboras will charge at the sand on leaves, and hard scape.

should i be worried about them eating the fine sand? they are super small but not sure if they would manage to swallow the substrate.

thank you!

Strawberry Rasbora I am struggling with restocking rasbora

3 Upvotes

Hi guys,
Iโ€™m hoping i can get some genuine helpful replies on this situation. This has been a stressing, haunting situation that i really need serious answers to. Iโ€™ve been hesitant asking for help here because i promise its worse the judgement iโ€™ve been fearing to get. But to start off, i have had an empty tank standing in my room for some months that i was planning on setting up again sometime. The set up i had before that was pretty crap. Then i set it up the first time and it still was. I did all of the research on the species i was gonna get: 4 amano shrimp and a school of rasbora, but then neglected to do any research on fishkeeping in general. I was stupid and i did everything wrong you could possibly do wrong; didnt cycle and after acclimating poured the store water along with the tankwater. Obviously this backfired insanely fast. One day passes by and my mom points out the water is cloudy. The tank has a lid so i didnt realize until later but the water also STANK and i was 100% dealing with a bacterial bloom and spike here. Then less that 24 hours later the first 2 rasbora deaths appear, then another, then another and after sometime the bloom finally sets down, my mom rushes to get me some equipment i honestly were better off with if i got them before stocking and throughout this whole situation i am in distress. i deeply mourn the fish i killed with my uneducated actions and i am in distress. My amano shrimp have been doing fine this whole time; they are molting as frequent as they should and graze on what they have. My veteran rasbora also still lives with no serious health complications but is glass surfing occasionally for every fair reason. The worst has finally passed and i get to calm down and in the meantime i improve the tank. My tank is slowly turning a lot more natural and i buy a lot more essential equipment. My parents really sympathized with me on this and promised to cover the costs of the fish i was gonna restock but i said id rather have them help me cover the costs of the equipment i wanted to buy to improve my tank for the remaining single rasbora and the 4 amano and that ill pay the restock myself. This felt like the most fair thing to do to the animals whoโ€™s lives i had wasted. I spend several months improving the tank first, i get tests, i figure out the right water to use as the pH was far too high, and more plants. Plants end up (despite quarantine) carrying 2 hitch hiking damslefly larves that i got off lucky from and then i finally decide everything is ready for the restock my lonely rasbora has been deserving. Then i make my next error: we go all the way to the store where i got them, which isnt local, just to find theyre not on stock. Bummer. But they can order them to come in their load next week and call me when they arrive, i stupidly get them the same day they came in, not realizing i was about to transport a school that had JUST transported into a store.. everything seems fine though, one fish is a bit shyer but not concerningly isolated, stressed or ill. They all swim, they all eat, my veteran rasbora has been swimming with them since they were still acclimating so im figuring this is way better than the situation before restocking. Then 5 days pass by and i cannot find the shy one. After a long time of looking i think to myself that its safe to say it has passed. Some hours after this the vibe in the tank completely changes. Every rasbora starts acting stressed, hovering in the plants. 2 days later another one dies and at this point i just know this terrible experience is happening all over again. Im sure the double transport was just too much for the weak one and that its death sent the rest of the rasbora that had came in the restock to their stress-limit and die in a chain reaction. from that restock only one survived just like with the first stock meaning i now have 2 rasbora left; one from both generations. They appear to be a male and a female and fortunately reducing the temperature slightly has stopped the breeding harrassment from the male meaning they co exist well territory speaking, but obviously theyre not thriving as a duo. I added more catappa leaves and my tank is way more tinted now (it wasnt as tinted when i restocked and i wish i did add the current catappa leaf at that time already) I switched to live food which really seems to boost their overal health because theyre both bright red more often, though i still feed flakes when i dont have hatched brine at that moment, which i rub into dust into a small cup of tank water, then feed them through a pipette which ive also found works better than sprinkling it into the tank. They eat well and my tank has gotten very planted overtime so considering the 2 somewhat traumatic experiences of losses i was thinking of phasing out the rasbora; trying to continue doing everything in high quality for this duo, but after they settled into being the only 2 left they have started to hover idle for most of the day. Sure they graze sometimes, and they hover in the only open spaces in the tank, but i wake up to them kinda just hovering there, and it still makes me sad. I dont know if thats normal, but the female (only survivor from the first generation) was more actively swimming and grazing during the time it was alone than it does now. The only think im glad about is that its not fully alone and also isnt fighting over territory, i have seen pretty much no glass surfing anymore, but it just looks off. Now im reconsidering restocking; im hoping ordering them from a breeder directly will prevent everything that went wrong in the previous tries, but at the same time i really stress that i will fail and kill a whole group again. Even though i messed up and i learnt from it, it feels selfish to try a third time, when this is about live animals that also have their own characteristic traits and lives. Please let me know honestly what i should do here. Ive also considered rehoming but i dont even think i can find anyone, and on top of that i dont want to build up more trauma in them by doing so.

PS: i am able to confirm that my parameters, tank scaping and overall tank health has not been a problem in the second error. The reason some rasbora disappeared after death is due to my amanoโ€™s eating their corpses, so nothing every really spiked. I also did not have a contagious disease running in the tank despite the stressed fish their immune systems weakening, i would not expect the remaining 2 to be physically fine if there was.

Advice New to fish keeping wondering if chilie rasboras are a good fit.

8 Upvotes

Iโ€™m starting up my first tank 10 gallon and am between 4-5 Medaka or 12 Chilies for a species only setup. I would prefer more fish in the tank obviously but I know chilies can be pretty fragile and I donโ€™t wanna kill any fish so Iโ€™m wondering if anyone experienced would steer me either towards or away from them as someone completely inexperienced in fish keeping.
Tank will Be heavily planted before anything goes into it, not rushing into this. I do also have access to unlimited RO water, which is good because my tap is 700ppm.

Advice Stocking a 14 gallon tank with chillis

I have a 15x15x15 inch cube that I kept a betta fish in for several years. I abandoned my initial project of keeping sparkling gourami in it, but am now thinking of a chili school and possibly one wild betta. I have around 4 or 5 chilis left from my 40 gallon, but in time they declined and have become very shy as I begun stocking larger fish.
How many would you put in my tank?

Advice Chili Rasbora with white spot is constantly chasing others

Enable HLS to view with audio, or disable this notification

14 Upvotes

Iโ€™ve had 10 chili rasboras for about 2 months now, and everything is going great except one thing. One of the chili rasboras has claimed a corner of the tank and constantly chases anyone and anything out of that spot. That specific chili has had a white spot on it for a while now, about 3-4 weeks, and I originally treated for ich, but it never spread to any other chili and it hasnโ€™t gotten worse or better. I am not sure if itโ€™s related to the chasing, but I wanted to get different opinions, since I think he might just have a missing scale and be territorial at the same time? Sorry for the crappy video, my camera does not like my tanks ๐Ÿ˜ญ

Tank size: 20 gal long
Tank mates: Neocaridina shrimp, pest snails, and an assassin snail.
Water parameters: 0 ammonia, 0 nitrite, <5 nitrate, 7.5 ph
Water temp: 78f-79f
History: A betta fish tank mate of them had camallanus worms and unfortunately passed, tank has been treated with expel-p three times and shows no signs of the parasite being present anymore.
Feeding: switch between micro pellets, vibra bites, and fluval bug bites 5 times a week, switch between plankton, mysis shrimp, brine shrimp, and daphnia 2 times a week.
