Hi everyone. Currently I have 3 rummy nose tetra (Hemigrammus Bleheri) and 13 Asian Rummy Nose (Sawbwa Resplendens) in my 23 gallon planted tank. About 4 male Sawbwa and 9 females. My LFS have a whole heap more of the Sawbwas in, and I would like some more. If I were to take the rummy nose out, how many more Sawbwas could I put in my tank? The Sawbwas adult length is 1 inch - 1 1/4 inches. I was planning to get a few more rummies to give them a proper school, but now that my LFS have more Sawbwa in, I want more. If I take the rummies out we will get some more for their school. Thanks for any suggestions!
