I'm very new to the world of aquariums. I'm a week and a half into a brand new 35litre tank (7.8gall-ish). Room temperature tank. One very small fantail goldfish and seven minnows introduced two days ago. I'm using a supposed bacterial cullture starter but I'm not convinced by it. I'll stick to 10% water changes daily until my filter is content.
Anyone done similar in terms of a fantail and minnow?
Hate to be the bearer of bad news but those fish are going to end up needing larger tanks. However there are lots of cool fish that would work and the members on this forum are always willing to help. Feel free to ask any questions you may have.
Yes the gold fish alone is too much for that tank. The minnows I believe won't work either. I can't think off the top of my head and cold water fish for this sized tank. Of you had a heater it would open it up to a betta, 6 galaxy rasboras, or 6 ember tetras
If you want to stick with cooler water fish, perhaps White Cloud Mountain Minnows. Not sure how many are appropriate for the tank though. But they are small, attractive and hopefully have a low bioload.
