Been thinking of getting into Discus. What would be an appropriate size tank if I wanted to merge my other s.american fish with 5 or 6 discus? Along with the dicus it would be 2 scalare, 25 cardinals, 2 apisto caucidens, and a green phantom pleco. Would a 75 be too small? Or an other possible conflicts with my current fish and the discus? If this is workable whats the lowest temp I could maintain? The tank would be in a drafty area where it takes alot of heat to keep temps up, and also for a comprimise with the others who might not do well in the usually high discus temps. Thanks for any input.
