Here are some details of one of the 90 gallon drilled glass tanks I used for grow-out. A friend sent me some fry a while back of some rocky mountain whites. These are a true-breeding hybrid of the Nile and Aurea and are one of the more cold hearty tilapia similar to Aurea (AKA blues). Some of these are snow white.



If you watch closely you'll see how the tank stays clean. Water comes in at one end and is removed from the bottom at the other end. Active fish make sure nothing settles. The T at the top is in case the bottom somehow gets blocked. It will overflow before the tank does.

Here is what feeding time looks like. They weren't very hungry. Normally I get wet.
