Yes and no.. while they are not wanting the same temps, they do appreciate the same basic water parameters. I'd say no.. didn't i?? Maybe once upon a time.. I'm about to move a stressed male gbr into a tank with 3 bolivians at 77° it'd be hippocritical to tell you other wise. You'll have to keep it at least 80 for the gbr. The others may go along with the plan??
