Ive just looked as throughly as possible without removing rocks and don't see a clone. The
BTA was been in the back of the tank under the rocks for a couple weeks and then in the corner behind the return for at least a week before tonight. At one time last week I thought it looked like a V was out of the side of it but it was in a difficult location to see, let alone photograph. I have a pix form 5/22 where the
BTA is open on a
LR near the front of the tank and it looks normal so, this could have happened anytime after that.
