i got rid of my big tank and now alls i have is my 30 gallon tank. well i consolidated and now i've got my valentini in my 30gal. he ate all my turbo snails and the algae is building in the tank now. the only thing that he couldn't eat or doesn't want is my cowrie and my shrimp. he likes to nip at some of the corals but thats fine with me cause the corals i have grow too fast. what kind of inverts can i get that are good at getting rid of algae besides the cowrie that can survive with a valentini? i can't get anymore fish either, i am at max load.
