What are these?? At first thought it was triops. But I found a few of them. Are they parasites? Found 1 swimming around in my aquarium few days ago. And today found another one attached to my goldfish fin. They swim crazy fast. Should I be worried?
It's alive and swimming fast as lightning. Few days ago I found one in my Hospital tank, bigger size which I thought maybe triops egg somehow end up in filter sponge or something. Today I found one in my main tank attached to my calico fin. Both hospital and main tank were using different sponge filter so I don't know where they come from. I try to look for more but can't find any. I'm afraid it's bad for my Fishes. I looked up Google but can't find anything about this weird alien thing.
