My apologies if you've seen this before but according to MY news server it 
hasn't appeared, hence the repeat.

I have a tank that is exclusively for mollies, except for 2 striped talking
cat fish.

The fish all seem well and healthy but I've noticed these little wrigglies
in the tank.

It's impossible to take a photo as they are only a maximum of 2mm long so
I've done my best to do a drawing. their colour is white and they seem to
stick mainly to the glass or rocks, they're not really free swimming. They
look a little like octopus or squid but have lots of long thin hair like
"strings" for want of a better word at their back end. (At least I assume
it's their back end).

The fish don't seem remotely interested in them,, either as food or anything
else.

The fish are mainly fed on flake and frozen but once a week or so they get
live bloodworm, occasionally brine shrimp and very very occasionally
daphnia.

Can anyone give me an idea what they could be so maybe I could look them up
to check and see if they're likely to harm the fish.

My little drawing is here:

They are probably hydra.

Relativly harmless but can catch and eat the smallest of fish fry.
As I recall some of the gouramies enjoy eating them.

HTH.

Found this on the PFK website...........

Hydra

A type of freshwater coelenterate related to marine anemones. They are 
usually found in ponds, but are sometimes introduced with plants or 
livefoods. Hydra are predators and usually feed upon small zooplankton like 
Daphnia. Their bodies and tentacles are equipped with tiny harpoon-like 
stinging cells called nematocysts with which they spear passers-by. They 
rarely do large fishes any harm, but can sting and catch very small ones. 
Hydra are sensitive to copper, so you can eradicate them with a copper-based 
disease medication. They tend to thrive in dirty tanks.
