Subject: Too many good snails?
Yoadie yo ho !!!

Based on a message from G.Tong to All,

Hehehe, the usual case with Melanoides tuberculata. You wake
up one night and find that there's more of them than the
gravel ;)))

 G> Now I wonder if having so many snails can be too much of a good thing.
 G> I'm thinking of their extra bioload (since added up, they may exceed my

Well, to be honest, I never had too many problems with these
guys, they don't have a large mass (notice that they're in
reality fairly small) and from my experience don't cause a
massive bioload. Also they have very very good metabolism
and really clean the bottom, and don't produce too much
waste. The problem of them dying remains, however, I had
massive deaths of this snail (it doesn't enjoy low pH too
much...) and it never caused any problems, it seems it's
really a very small mass...

 G> Besides loaches, what other "natural" means of control are there?

Loaches won't control this guy that easily - all other
snails, yes, this one, since it moves below the substrate -
not really. To be honest, the best method is turn off the
light, turn down the oxygen for a while and scoop these guys
off the walls then, alternatively give them a tasty bite to
get close to (of course when it's dark) and then get'em
while they don't know what's up :)
