i agree. but i also love the sick coloration of them.I voted for the Jewels because of the adult size. They stay the smallest so the 55 would offer them more room than a fish twice it's size. The first three have the potential to get to 6in or more so the tightness of the 55 would really show it's cramped quarters vs a fish that is only 3in.
You said as a center piece, what are the other fish you’re planning on keeping?
Do jewels if you want color, but a convict if you want a hardy, dependable, interactive fish. Jewels are also that way, but it’s hard to really beat a convict for the best smaller cichlid.
