I'm feeling very down that I have yet another illness to deal with. I've had the new fish in the new tank about two weeks. I had to treat for ick with in the first couple of days but lost the fish anyway. Now it appears one of them may have internal parasites. While all $40 worth of fish looked happy and healthy the day I bought them, that doesnt seem to be the case. I have dealt with verious illnesses in the old tank too. Seems there may not be a healthy lfs in my area as I have bought from several different stores, but there always seems to be something wrong that I don't see in the store. True, I do not have an isolation tank for when I get new fish, but at this point, a sick fish is a sick fish where ever it dies, it is still a dead fish and a sad me. I feel as though I should just treat for all manner of parasites/fungus as soon as I arrive home. How do I get a healthy fish and how do I keep it that way?
