As of now my 75G is in between stocks and houses some giant danios, some juvi cichlids, a striped raphael cat, a gibbiceps pleco, and a yellow bullhead. Pretty soon I'm getting rid of the cichlids and after that the danios and I hope to have the raph and pleco moved to different tanks soon as well. I've gone over many native stock options for this tank once I have it opened up and I considered trout. Brook Trout to be exact since they are the only PA native trout other than lakes which I'd love to have but I don't have room for a 600 gallon. I know brookies could possibly outgrow the tank but honestly I never really catch them much bigger than 12-14" and I think it'd take a while for them to outgrow this tank, when they do hopefully I'll have my 180 gallon native setup in my basement for them. As far as temp concerns, I'm willing to invest in a chiller and I was thinking about making a DIY one I saw UaruJoey make to save money. And for current I'd have a strong powerhead and an airstone. There would be tankmates though since I'm not parting with the yellow bullhead in the tank and I have a 6.5" white sucker in a different tank that I'd grow out in the 75 as well. If there's still room after that I also think it'd be cool to have a Lamprey, they're awesome fish I just worry about my bullhead trying to eat one (however he hasn't touched the cichlid fry in with him months later!). After a yellow bullhead and a white sucker (and possibly a small lamprey but not for sure) how many brooks could a fit in the 75G until they hit 12-14" (then I'd upgrade)?
