I'm told that malaysian trumpet snails are beneficial to a planted tank. What's everyones take on this? I'm curious because I know I've got a ramshorn or two in my tank (puffer keeps the numbers low), and I've heard that malaysian trumpets snails combat them by eating their eggs.
I have MTS' in lots of my tanks - they don't eat the plants and are great at burrowing through sediment. I don't know about their nack for eating ramshorn eggs but I would guess this is a good possiblity. Puffers enjoy MTS' as well.
Most snails are pretty neutral occupants of a planted tank. They seldom eat healthy leaves, preferring the decaying and dying leaves, since these are easier to eat. I have a mix of snails in all my tanks.
I had thought that the MTS in one tank were overtaking the pond snails as the total number of snails seemed the same (100+?), but the balance shifted from all pond snails to MTS plus maybe 3 pond snails. Now that has shifted back and the pond snails are returning.
I had suggested that perhaps they were eating the pond snail eggs, back when the pond snails were nearly extinguished in this tank.
