I have recently purchased a 120 gallon long aquarium. It's deimensions are 5'x18"x26". i would like to keep a pair of green terrors, a texas or green texas cichlid, a jd, along with a common pleco and a small shoal of pictus cats. i was curious if this settup has any potentia, or if it will be too problematic. I will have a 20-30 gallon sump with a 1000 gph pump on it.
