For me I am cruising along on a flat plateau. I have 5 tanks....150, 135, 75, 55 and 20 gallon. I have my big cichlid tank, active community tank, my archer fish tank, my breeding tank of t. Maculipinnis and then the 20 long which is basically my qt tank but right now is a beta tank lol. I don't have any plans to change stock as I'm happy with the variety I have and tend to keep my fish for the length of their lifespan. I do want to get a couple more archers as I am down to only one now. And the mention of flagtails reminds me how much i want to get another one. ?
