Just seen it. Just took it out. A slug like creature with two antenne that was sending up puffs of smoke. Whatever the stuff was the fish were eating it. Should I keep it or kill it?
Okay found a picture and it's called Stomatellas. If what I read is correct it's harmless and can be put back into the tank. However, I will await an answer from someone.
Not my picture, googled it but it looks exactly like it. Do you know why it was belching puffs of stuff from it mouth. Defense mechanism against being eaten by the fish?
If it was releasing eggs that may explain why the fish were going nuts eating them. I could see it really up close and it was coming out of it's mouth(front) area. A little puff everytime the fish went by. So I wasn't sure what it was doing.
