This is a poll for people who have trouble with Malaysian trumpets (MTS) in their fish tanks. I'm gathering anecdotal data to see if it supports a friend's loose hypothesis. He runs a large laboratory in the biology department where they study tropical fish. MTS have gotten into some of the tanks, and they are a real problem in experiments where the researchers need to track the amount of food that the fish eat and the waste that they produce. It appears that the fish will not eat the food once the snails reach it. Our friend hypothesizes that the snails leave some kind of cue on the food that keeps the fish away. So for those of you who have and MTS and tanks with fish that graze, let us know if they will eat after the snails have passed through.
