I am thinking I might like to get a second T, but really only if I could devide my G. rosea's enclosure. It is a 5 1/2 gallon tank with a metal screen cover. Could this work with another similarly sized T, or would it be too small? And if it would work, any suggestions on what would T's would work well? My only real conditions are it must be the same or smaller than G. rosea, and it needs to be even tempered like the rosies too, and need a similar habitat.
