Totally agree. Looks really weird and disgusting.Wow! Um... No idea personally but I'd have freaked if I'd caught that in my tank!
I see. Could I know did you add anything new lately to the aquarium? And when did you first see this bug?I seen it in my tank the other day i thought it was a small fish then i saw the eyes and legs i crapped mysel lol
Totally agreed!that thing is cool, i would have kept it
Almost certain it's a dragonfly larvae. Here's another pic. Is this it!?
