I personally think these snails are the workhorses of the planted tank. Much like earthworms in an outside garden. They burrow through the top inch or so of the substrate, so they help oxygenate plant roots as well as help prevent hydrogen sulfide pockets. Also, since they're livebearers, they won't leave any yucky snail egg casings all over the tank walls and plants.
As with most snails their population does tend to explode from time to time; especially if you're overfeeding the fish. They're easy to bait and remove from the tank, however; I use sinking catfish wafers and place them inside a fish net resting on the bottom of the tank. Just lift the net in a few hours and you'll have tons of snails inside.
As stated above, they seem quite useful in a planted tank, as long as they are kept under control. Once a week I run out all the lights, wait an hour and then come back in and kill all the babies on the glass. This helps with population control. I call it the 'Glass-N-Smash' method :)
Shrimp are great at eradicating an exploded population. These snails are sold on the internet for being great algae eaters. The Malaysian Trumpet Snails are pretty sweet snails as long as they aren't eating up your plants' leaves! They're like horses plowing a field sifting gravel and fertilizer medium.
I have kept gravel from an old aquarium that had MTS in it in a bin in my garage for 15 years, washed it out and started a new tank with it. few weeks later i have baby MTS crawling over the glass. Amazing species
I live in Attalla, Alabama and caught these last year at a creek near my home. The bear live young, don't over populate, and burrow in the substrate keeping it very clean. I do, however, have to pick the snails that came in on my plants off the glass every day to keep their population down. I'd like to be rid of them but I'm hesitant to get some assassin snails for fear of them killing my native snails.
I agree these are a must need for planted tanks, but they do cause problems for me. Any bulb that I'm trying to grow that still floats will most definitely be flung upwards by these guys, also, trying to root Wisteria is near impossible. Finally, I like to put in a few Assassin Snails to liven up the tank and watch them fight to the death.
I accidentally bleached some of these, thought I got them all out of a tank and turns out there were a few micro ones. I let the whole tank sit in bleach. When I filled the tank after sanitizing, there they were climbing the glass. I don't suggest that, but they are hardier little buggers.
I can't say I could honestly do without these little guys. Ever working, ever tunneling and ever cleaning... These guys are the constant gardeners in any planted tank. I keep these in all, repeat, ALL my tanks. They do an amazing job turning the sand in my tanks, and creating an absolutely perfect environment for my plants to thrive in. If you could see some of the root structures in my tanks I think you'd all agree. ;-)
