the ray will love the higher temperatures. The del won't mind it, but I don't know about the jar. If these are the tankmates, you might be better off keeping the tank 82-84F. This is still great for pbass, but makes it more comfortable for the other tankmates.USMCtanker;1625519; said:ya im thinken of uping the temp and keeping it at 86 or so, i have a moto ray, del, and a jar also in there so they should be fine at those temps as well right?
