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.

Wrigglies are usually some member of nemotodia, like planaria. From your
picture, I would research the Coelenterata phylum, particularly Hydra
(americana, vulgaris etc) or Chlorohydra (viridissima..). Drop one of
your gouramis in there for a week ;~), they usually like em.

Mmm - there isn't anything that's EXACTLY the same in those but Hydra
vulgaris is the closest.
Tend to be of the mind that "if it ain't broke etc etc" but will leaving
them to sort themselves out harm the fish?
Not keen on swapping gouramis over - mollies are in salted water and my
gouramis aren't used to that.
