I have a 50 gallon tank with a clown, yellow tang, 3 damsels, hawk fish and false eyed puffer. I am looking for a bottom feeder to pick at food that the other fish miss. Any advice?
Most bottom feeding fish don't last long (because most will deplete the bottom of food and starve) So just go with a large population of nassarious vibex snails, and ditch the coarse gravel!
Do you have corals in this tank?
I notice you have a "false eyed puffer" (?) and a hawkfish. If you have no corals, then I would suggest a large hermit crab like the red starry hermit. They are large enough to fend off the puffer and hawk and the large hermits do an awesome job of cleaning the bottom!
If you have corals then forget I said anything as the larger hermits will sometimes eat corals!!
