The aiptasia probably came from your source of chaetomorpha. They’re transparent and blend right in, and most people don’t care if it grows in their nutrient export.
Now that they’re in your tank it’s gonna be tough to eradicate. But as others said it’s not the end of the world, there’s many biological controls.
Just use this as a lesson to pay more attention to adding things in the future
I believe the best option for pest free chaeto is a seller that specializes in selling macroalgae and specifically advertises that they sell pest free chaeto.I have to agree that I think it possibly came from my chaeto as well. The downside is my wife and I were very cautions and bought our chaeto from a LFS close to my work to try and avoid this issue. Again quite bummed.
A couple small aptasia have popped up, and I quickly hit them with F-Aptasia. So far 4 days, and no sightings. We are being hyper vigilant.
They won't keep it with other corals either. Kinda like their own isolated systems. If it's in a sump system that corals are added to in lfs always a chance of getting aptasias in it.I believe the best option for pest free chaeto is a seller that specializes in selling macroalgae and specifically advertises that they sell pest free chaeto.
