This is what I am going for. Pooping fish, pest hunting fish, pretty fish, cleaner fish, more pooping fish, more pretty fish, a couple extra cleaner fish, shrimp, hermits, and snails. Then maybe a few more pretty fish thrown in for good measure (after all, pretty fish poop too!)Although I am assuming part of this is sarcasm, I have fish in the system for more than fertilizer, i have worker fish. Fish to eat the algae, fist to poop and make waste, fish to eat hitch hiking pests...every now and then i have fish to enjoy watching them swim
