Anemone ID and others

[Devin2589]

Live rock from gulf live rock and kp aquatics. Need help identifying what’s on them.
2 different anemones. Coral? Sponge?

 

[Spare time]

First two are aiptasia

First two are aiptasia

I believe they are majano rather than aptasia

I believe they are majano rather than aptasia

I’m 99.9% sure they’re aiptasia. The others are a macroalgae of some sort and the last looks to be a coral (I forget the species, it’s common on kp live rock, it’s similar to a leptastrea).

 

[damsels are not mean]

Top two are definitely aiptaisia. Ugly and spindly. Majanos are at least pretty, they look like mini bubble tips, and are not always considered a pest by everyone. Sometimes people even buy them. You want to kill those aiptasia ASAP and hope more don't pop up. They usually do, but not always. I had a large aiptasia anemone come in on a coral once and I nuked it will kalk paste. Haven't seen any more in 10 years. But you have to act fast or it will start to establish itself in the tank.

Bottom left I agree looks like a macro algae. I am no expert but maybe it is this? Called Ochtodes and is common in marine planted tanks due to its striking blue color:

I hear it grows like a weed and can choke other things out. Do your research on it and consider removing.

Bottom right I am not sure. Some sort of stony coral or coral skeleton.
