Alright, so I have my two little lion heads in a 20 gallon tank. They are both very small (one is maybe 3” the other is around 2”). What do you think if I added another? I know it’s already really small but I honestly can’t get enough of these fish. The two that I already have I’ve had for months, since the summer, and I haven’t noticed any growth in wen or length since their purchase. Let me know what you think, I’m happy with what I have if it’s not possible. Thanks!
