Hello all.

This was in my corner overflow for about 8 months, no idea where it came from but I left it alone. Recently it un-attached and got sucked down the over flow ending up in my sump.

I fished it out and put it into my display, thinking it was some kind of aptasia type thing that my copperband butterfly might munch on it (he polished off hundreds in about a week, now trying to grow aptasia in a 3 gallon).

if it isnt an aptasia it is a majano anemone. Another pest anemone. I could rid of it if I was u.

It looks like a bleached aiptasia to me

Me too. Prob from lack of light...?

Could an aptasia sit in my corner overflow for 8 months without even 1 more being spawned in the corner?

It's gotta be about 8 gallons of water in there, I would think after 8 months, with one big aptasia in there, it would be wall to wall aptasia, no? Especially because no predators could reach them, I think they would take off.

If the food was abundant and water conditions ideal (re high nitrate/ammonia) then they may replicate like that but just because they haven't is no reason to assume this is not aiptasia.

It is clearly some kind of glass anemone and you may have a ticking time bomb there.

Yes, it is about conditions that make it right for replication. I had a large aiptasia in my first tank for about 12 years. Over that time, the population grew from one..to two. I guess the conditions were never right for it to multiply.
