Has anyone ever had something like this just grow in their tank before? What on earth can it be?
any guesses? sorry the pic isn't that great but essentially there is something white or cream colour inside a translucent sac of some sort.
it is grossing me right out!
The thing in the rock/wood just right of the middle of the picture?
It looks like a bacterial colony around a big chunk of uneaten food or bacteria over a dead fish. I would lean more towards the uneaten food, personally. Possibly an algae wafer? What food do you feed?
The white goo? yuk. I guess you dont have any snails. I remember when I had fish and when they died, my shrimps would be over them, after that, all the snails would be over them. After a while, only the bones were left. Since you dont have anything to devour it down, I guess fungus is there to do it.
