Okay so I have been searching for this fish and finally found them at a pet store that is about an hour away from me. The problem is they are really small. Do they grow quickly? I could house them in a 30gal until they become big enough for my other fish. Currently setting up a 90gal was going to set up a 55 but opted for the 90 to house my Frontosa, Yellow Tail Acei and 2 Electric Yellows. What are your thoughts? Any other good suiters for this tank?
