i turned on my light late one night to see how my malasian snails were doing and found small, thin, white worms on the glass. Anybody know what these are and how to kill them if their harmful. thanks

Hi,
Most of them are benign and in some cases the fish
will eat them if they can find them. Usually they
spend the daylight hours buried in the gravel and
come out only at night.
They are an indicator that the tank needs maintenance.
Especially, the gravel vacuumed. When you vacuum the
gravel, mentally section off the unplanted tank into
four sections. Then, depending upon your bio-load,
vacuum a different section each month so that every
quarter, you have cleaned the entire tank. If your
bio-load is higher, then do a section every other week
or every week. The purpose behind not doing the entire
tank at once is that most of the bacteria that make up
the Nitrogen Cycle are found in the gravel. A wholesale
overhaul would ruin the colonies and the tank would wind
up recycling again. The delay allows the "damaged"
(cleaned) area to recover before the next section is
worked over.

Just get a good old fish net and get um' out. Thatll get rid of them top side but like Frank said you need to do a gravel vacume.
