So I just picked up a 75 gallon tall tank, approx. measurements are 48L x 12D x 30H. Haven't set anything up yet, just trying to get ideas on future inhabitants for this tank. I hope to have a nice community tank with activity at all levels within, but, I have never had a tall tank before, at least nothing so large. Any input about species to fill it with will be greatly appreciated. If possible, please explain why you would choose species you may be suggesting. Thanks in advance.
