i had ich...best to know why you got it first, it seems unhealthy fish get it, my reason was crappy water quality...anyway i wacked the temp up on my tank but not sure thats a good idea for you as youve got plants...someone on here with more knowledge will help, good luck, claire
raised temp has no need for meds i was told, ich stops reproducing at that temp...so leave it at 30 for ten days...hey presto...ich gone...
