What is the little organisms crawling on the side of my tank glass?

Question

they r very small and look like little maggots and it looks like they eat algae...but idk....can they hurt my fish.....

Answer 1

they are call red nematoads NEHMAHTODE

Answer 2

how big are they? Are they like tiny little white worms (tubifex) or are they like flat worms (planaria) or do they have shells? (snails). None of these are bad for your tank or your fish, though they can be gross to look at.

if you really get grossed out by them you can remove your fish and use an invertebrate killer in the tank...  but I don't recommend it. it absolutely destroys your cycle.

Answer 3

i think there small gold (something) snails but they will not hurt ur fish.

Answer 4

Do you have any live plants?

It sounds like Planaria, which is completely safe. Your fish may try to eat it but they will otherwise ignore eachother.

Do a google search for Planaria in Aquariums and you'll get alot of results including pictures and videos.
