Dude, you can see everyone's thoughts on the stuff. Would you find a tank full of this stuf and it can get big, how attractive is that. Or pretty corals?
While every thing everybody has posted is true.There is only one reason I can think of where a tank full of aiptasia would be beneficial.And that's if you want a tank with a Copperband Butterfly or a Batfish.since a diet of aiptaisa seems to be what it takes to keep those fish happy.
