i decided to make an account here after purchasing my blue tang at petco and my other fish (lionfish, yellow tang, & foxface) started to be aggressive towards it and just nipping, pushing it and cornering it. im hoping by having this account that i can get many opinions to help make my tank successful and safe for all my fish. i currently have 4 tanks a 55g with goldfish, koi, and sucker fishes. i have two 20g..one with a maroon clownfish and a chocolate chip starfish. the other saltwater 20 has two mollies but we use it as a qt tank for now. then i have a 150g fowlr
tank with a snowflake eel, porcupine puffer, yellow tang, blue tang, lionfish, two snails, and two shrimp.
