75 gallon question

Thorichthys species live in groups in the wild, so I would recommend against adding a single Firemouth. Of course you can do what you want though, it's your tank.

 

[ehh]

If going with convicts, it would probably be better to get a male/female pair.

Also, you may want to consider other Central American fish like swordtails or mollies as tankmates. Tiger Barbs are Asian and Cory are South American. Corys are going to want warmer, softer, more acidic water than convicts.

Using fish from the same region together means they will thrive in the same water conditions, and it will also be aesthetically pleasing as a "biotope" even if it's only a rough approximation.

Convicts do fine in anything. High ph, low ph, cooler water, warmer water, Gatorade.
