Hi everyone, beginner here looking for some assistance. Does anyone recognise this behaviour? I only noticed it this evening, she is looking quite thin as well from my untrained eye. Looks like a parasite of some kind to me, really hoping it isn't contagious as I don't have a quarantine tank.

Unfortunately I do not have any test kits at home, however my other honey, nanofish (psuedomugil luminatas) and shrimp all seem to be healthy. The tank is cycled and everything has been running smoothly for a few months.

Any assistance would be much appreciated!
