Chili Rasbora Tank Recomendations

26159 5
Hello everyone!

I currently have a planted 2.5 fluval set up with a few cherry shrimp and a horned netrite snail.

I'm really wanting to add a few fish and have fallen in love with chili rasbora.

I have "The 101 Best Freshwater Nano Species: How to choose and keep hardy, brillant, fascinating nano fishes, plants, and invertebrates" book and it lists that the minimum size for these little guys is 2.5 gallons.

My question for everyone would be how many could live happily in a 2.5 gallon? I know they are schooling fish so I want to make sure I get enough for them to be happy. I also have a 3.5 tank I want to set up as a planted tank as well, would this be a better choice?

If you all think these tanks are too small, let me know! If they are, I'll just stick to my invertebrate set-up ^_^

Thanks in advance for any help!

I added 6 chili rasboras to my 10G RCS tank not long ago. They are a beautiful addition to my tank due to their bright color and liveliness. 10G is clearly enough room to hold 6 chilis; in fact, judging from their behaviors there is enough room for 6 more. Although they are peaceful community fish, the tank needs dense plants / hiding places for small shrimp. I have seen my chilis chasing after shrimplets, but I have never seen anyone being eaten. My shrimp colony size has been growing.

I suggest no more than 3-4 chili rasboras for your 2.5G or 3.5G. Introduce them into the tank and see how they do. You should have some plants to provide hiding places for RCS; on the other hand, plants should not overcrowd the already limited open space for the chilis. If possible, I still recommend to go up to 5G or 10G - both rasboras and shrimp would be happier!
