Started a tank roughly a month ago, it is a 90G reef. It has finished the cycle and has very very few diatoms left that the snails have been feasting on. I have 7 turbo snails that have been in the tank for about a week and a half. I plan on getting quiet a few more once they are needed. but i was wondering if it is safe to move my 2 tomato clowns into the tank and out of my 20 gallon. Thanks!
