Back when I worked in the pet industry years ago, I never treated people like this. Though I was an exception. I actually knew about fish. Most of my coworkers were kids who never kept fish.
alright even a 55 would not be enough for all these fish, they will get very big and quick your best bet is to return the fish to the fish store and buy a piar of convicts or a single green terror these fish are really more suitedd to your tank
The dovii alone will need at least a 125 gal. tank for one. The others may do well in a 75 but either way . give the jewel more room & for it's size it will swim circles around the other fish. I had a 5 jewel many years ago kill a pr. of 6-7inch cintrinellums (then thaught to be red devils) & a 5inch male convict in 24 hrs. in a 55 with just the 4 of them. it was a similar thign guy at store said it should be ok. pet stores either don't know or just want a sale. i remember one time I saw someone put a butterkofri in with some peacocks the peacocks were beaten half life in half-an-hour.
