Hi.

I have Japanese Trap door snails. Well I HAD them before, but then they abandoned their shells and then I couldn't find them anymore.

I have one LARGE angelfish, black skirt tetras, gouramis, pleco and a new oto cat.. although he or she hasn't really been in my tank when my Snails existed inside my tank. Although now I don't know how they "mysteriously" died :S

I do a water change every wednesday and a full siphon every Friday. So I have no idea what's wrong with my tank :S I have NO ammonia, I have live plants, and I always clean my filter all the time (with aquarium water) and I don't know what is wrong. Even my fishes aren't aggressive to any of the other inhabitants in my tank.

Please help me.

thanks.

How many did you have? What is the tank size, pH, and temp? What did you feed them?
(sry for all the Qs but I need to know this info so I can possibly pinpoint the problem.)

Japanese trap door snails can't abandon their shells. They are as connected to their shells as a turtle is to its shell.
When they die, many fish will pick them clean rather quickly, though.
My guess is that one or more of your fish harassed them to death. I had some trapdoor snails that died when my gold barbs kept pecking at their eyestalks.

I haven't checked my pH yet but I know that it is at a good level because my angels would've felt sick or any other fish in my tank would've felt sick too. my ammonia is always at zero, my nitrites and nitrates.. I don't know yet, but my nitrites are slowly declining because I have live plants in my tank.

I guess my fishes have harassed the snails. What type of fishes will harass them?

Oh. I haven't had any barbs in my tank for a long time because I got rid of them. Especially when they were pecking at my angelfish's fins. I had my trapdoor snails in my tank because of the algae and I hoped that they could be able to clean my tank for me. Well the plants only I guess.

I have an Angelfish that continually pecks at my snails. I had to put him into a large breeder net for a while until his dominant aggressiveness subsided after I added some larger fish.

Oh. So did you add some severums? or other fish? What fish did you add?

I added two large angelfish that grew up together. Whenever the other angelfish started becoming aggressive the two new ones chased him around. After a pecking order was established no other problems occurred.
