Too many fish?


Hi all! I've got a 30l planted tank that I built mainly for shrimps. I've been using my betta and snails to cycle it but the betta will be moved to a different tank soon. I'll be getting a bunch of neocaridina shrimps soon and I have 4 pygmy corydoras and a small mystery snail. Would it be too much if I added some chilli rasboras to the mix? I was thinking about 6-8 rasboras, but I'm not certain if that'd be overstocking the tank. What do you think?


It is quite a lot of fish for a 8gal tank.... Overfeeding or missing a water change could cause problems quickly.

For me the minimum tank size for those fish would be 10gal, but they would be more comfortable in 15-20gal (70L so pretty much double your tank size).

Only if your tank's filtration is not enough strong to support the demand. If your filter is exceptionally strong, than everything is ok.

Imo it's not about how many fish can your filter handle. But will the fish be happy? Raspboros might be small, but they swim quite a bit. They need more space to spread out. Cories are happier in a bigger school as well, but you could probably get away with the cories only. I wouldn't add the raspboros

I'd skip the chili rasboras and double the number of pygmy corys instead. They do better, and are more interesting to watch, in larger groups.
