This one was free to me, given to me by a friend who just wanted out of the hobby.zunedog31 said:How much does a tank like this cost to make?
Couldn't have said it better myself, lol.cm11599ps said:They don't have to feed because this is basically just a tank containing coral. Most of the coral we keep have an algae called zooxanthallae living in it's tissue that form a symbiotic relationship with the coral. The zooxanthellae converts the energy from our high power lights into food for itself. They are very efficient food producers that they actually produce too much food. This excess food is then utilized by the coral. The coral offers a predation free area for the zooxanthellae to grow and the zooxanthellae return that favor by feeding the coral.
Not all the coral we keep have this symbiotic relationship but most of the ones you see do. That's why you the OP states she doesn't need to feed the tank.
I also see what appears to be an astrea snail on the front glass. They will munch on the algae that naturally forms on your glass.
The only problem I see comes from your fan worms or "feather dusters." These guys do need to be fed things like rotifers and plankton to survive. The "feathers" they extend actually capture tiny food particles from the water column so I would strongly suggest you reconsider the "no feeding" aspect of this tank if you want to continue with the feather dusters.
Other then that, looks good.
