I got a new acan and i have it next to another one i got over a month ago, and i am not sure what is going on here. There is a whitnstringy thread going from one to the other.
The new one is on the right.
I figured it out. My cerith snails layed eggs all over the place and it looks like a string of them came off the glass and floated around the tank until the acans just happened to catch it.
