The tank is 8 months or so, and ill get a full tank shot but it doesn't go much further than the colt coral on the left. Its a biocube 14 and the corals have grown up a lot since i got some of them because i buy most of them for cheap cause there half dead. 4 months ago when i got the brain it wouldn't even get 1/3 that size now its at least 5 inches. And i know the cow fish is a bad move in that tank but 5 months and no problems yet, hes only in there till he can handle his own in a fish only tank at my buddy's
