Reply To: Small, thin worms in breeding tank.
Unfortunately they seem to be in both my tanks.
I tried to get a picture, but there just wasn’t enough contrast because they blend in so well with the water and such. Even on supermacro mode the camera just couldn’t do it.
Not ich? Well thats a relief. But even if it is something natural and harmless, it bugs me that there is something in the tanks that I didn’t purposely introduce…Kind of like those little parasitic snails I got with the new plants the last time I bought plants…
On the bright side, when I was trying to take a picture of one of them in the other tank, my beautiful betta, Aquila came by and snapped it up in that big mouth of his! 
I doubt anything could survive the stomach acid of that fishy.
