HI Ihave noticed some odd looking creatures in my fish tank They don’t appear to be fry of any sort and the fish don’t eat them so not daphnia. I was wondering if anyone would have any idea what they might be?
They seem to like being on the surface of the water when it is dark, but when you put the lights on in the morning they head for the bottom the tank and hide in the stones.
It is very hard to describe what they look like. to the naked eye they look like small greyish dots about 2mm in size but if you look at the through a magnifying glass they appear to be clear with a few veiny lines almost round in shape. No definite head / body, no wing cases, possible legs or antennea but magnifying glass i have not really strong enough to determine.
