Hi i am new to this posting thing so here it goes. I have had this small hippo tang for about 2 weeks now and out of no where he appears to have ick. The tank he is in only have hermit crabs, snails and a 2 corals frags in it. It is also a 20 gallon setup that has been running for a little over 2 months now. I don't have a lot of money to be putting into another tank just to cure the tang. If anyone knows anything that may work in my tank to take care of the ick please do let me know.
