I have recently been posting questions regarding setting up a 29 gallon apisto tank. One question that I am unsure of is the actual purchasing of apistos. Is a trio or pair of apistos recommended for a tank of this size. I do not want to have on outcast female, and will go with a pair if this is likely to be the case with 3. Also, is it generally recommended to purchase a larger group (how many?) to ensure that a pair/trio is attained? I recently saw some rather small apistos (caca. and borelli) for sale at a lfs, but they were of very small size (<1/2") and am unsure of what to look for in fish of this size to ensure that I purchase a healthy group of fish. Thanks for all of your help everyone, you have really helped guide me on the long process of setting up an apisto tank properly!
