you are right. the only other solution for snails is the one you took. I might have to do that as well. I can"t figure out who is breeding anymore, there are so many of them. I curious about something, though. And it"s off topic. But I was wondering how people treat tb now. I had a problem years ago, losing one fish every week or so. no sign of ich, clamped fins or any other problem. I lost a breeding pair of angelfish, and that got me mad. Come hell or high water I was going to figure out why they were dying. Not much on line about it,so I went to the library and took out every book on fish disease I could find. After much very dry reading, I figured out it was picine tuberculosis. back then pet stores sold isoniazid. this med is still used on people in some parts of the world. anyway, tb is transferred through cannibalism,not through the water. the med was expensive, so after a while I watched the fish more closely. At the first sign of a problem the got the fish the hey out of the tank, and the cycle of death stopped. So, what is the standard treatment for tb now? Do they still sell a medication for it, or do people just use quarantine as the standard treatment. I"m curious to know.
