Hey guys I want to know if a 180 will be a large enough tank for when these fish are adults. I currently have a 8.5" kelberi peacock bass, 13" tiger oscar, and a 12' pleco in a 120 gallon and I plan on getting into reticulated stingrays again which get 12-14" wide. I want to know if a 180 gallon can fit these for life. And possibley a clown knife (I don't have one) But even I doubt that since clown knives I heard get 26-36" and I've personally seen a larger one. Thanks!
