The type of Cichlids I get can kinda be determined by which tank they go in. And by small I mean the ones that at full size don't get over 6". I had figured they'd have to go in the 55g, but was just trying this other option out as I'd love to plant the 55g.
The other factor is that I have the 29g set up with gravel and normal lighting. Currently the 55 tank has no substrate and a very dirty top and light.
If I plant the 55 I have to buy a new light anyway and I have a bag of STS to put in there.
If I plant the 29 I have to take the gravel out, throw the good top and light away, and clean the 55 equipment best I can.
In short, it would be less hassle to keep the 29 the way it is and put the fish in there, but I just don't know if it's possible.
