There is 7 of one species, 6 of another and 5 each of two others. The two types of brichardi will hybridize if kept together and so will the red rainbow and illangi. It's fine if you just want to watch the fish with no breeding plans. It's just not how trophs are commonly kept.
Picture B is a wild female Crenicichla notophthalmus which is a dwarf pike species. The species is fairly laid
back for a pike species except when breeding. It will eat anything alive that is small enough to fit in their mouth.
Bill's rack looks as though it is assembled with carriage bolts and nuts. You may be able to disassemble in a couple strategic locations and reassemble once it is downstairs.
