worm question and a few other strange things.
So a few strange things have been happing in my tank the last couple weeks. I had a problem with pest snails but I have almost got that under control. Yesterday I found one of my female amano shrimp dead on the floor ( !across the room from the tank! ). That is actually the very first loss in my tank ... ever. I see my shrimp swim to the top of the tank now and then .. but do you think they want to escape?
Then today after I got home from work I found two trumpet snail shells on the floor 2ft from the tank. I have never seen one trumpet in my tank. I thought it strange to find one shell, but even more so when I saw the second. So I took a few mins and looked over my tank. Nope, there were no snails.
But that leads us to the reason for this post. Worms. I need some help guys if you can. I found theses things that looked like worms in my canister filter. I tossed some down the drain and saved one in a jar. The water is extremely toxic because I keep putting pest snails in there with it and they keep dying and their shells rotting. But I am not sure what the worm really is or where he came from. The scary part is there are more in the tank I cannot get. They swim like a snake and hide under the gravel. When I was looking for trumpet snails I saw something move by my plant roots. So I watched and as a piece of food floated by, a gray point came up out of the gravel, attacked the flake food and then disappeared. Then it would come up under one plant and go down by another. There could have been more then one. The worm I captured must be the same kind. He is gray (ish) and moves like an inch worm, taking one end of his body and stretching out really thin and far and latching on to the glass, then pulling his back end of his body to him. But instead of bending his body he seemed to shrink and get fatter in diameter. The fish know he is there and my danios spend all day looking for him in the grass. I am concerned he might be a parasite and try to hurt my fish. Please let me know what you think and if you have any suggestions to get rid of him (them).
