Pix & ID: Critters that come in your rocks: the good and the bad.

Ive been gone a this past week on vacation. A friend has been feeding the fish and sorta taking care of the tank. I had the lights off tonight and was looking around my tank with a flashlight. I found 4 different spots with aptasia growing. What's the best method from getting rid of these guys? Any particular reason these guys just showed up? Thanks

This squishy little fella?

This squishy little fella?

Weirdly inconsistent post appearance behaviour on my first request post, hence the quote. Tapatalk's fault? Not trying to come off as too needy...

Anyhoo, howsa about this guy? Ball Anemone? It's about half a centimetre in diameter, and there are one or two others around the corner, inside a live rock hole. He caught some food yesterday and proceeded to eat it up right quick.

Hey all,

Been searching the whole net for this, but so far, no luck. Maybe one of you old salts can easily make an ID for me? It's this black, net-looking stuff on my live rock: it's hard, and not at all slimy. About an inch square in the pic.

I broke some off by poking it with a toothpick, and then immediately regretted it as it drifted off (sank, mostly) to potentially colonize other areas of the tank.

Anyone know if it's anything to be concerned with?

Thanks!

it has been noticed that bristle worms have eaten clams

Dead or dying ones. Unless it's not a actually a bristleworm but some other type. It's kind of like saying maggots killed a dead animal on the side of the road just because you saw them eating it.
 
Any ideas what this is. It's kinda soft, almost rubbery feeling.

Can anyone identify which type of Aiptasia?

Can anyone identify which type of Aiptasia?

Hello, I'm hoping someone can positively identify this type of aiptasia. It looks very much like Bartholomea annulata (in the aiptasia family) and from the literature I've read, this type is widely variable. These I'm showing range from approx quarter size to a silver dollar size when fully open. This is not the type that is widely hated in the reef community. I have about 8 of them that came in on some florida live rock about 10 months ago. They don't spread, or at least, not easily and have not created any problems with my other inhabitants. The literature I've read also states that Bartholomea annulata is by far the most common anemones in the Caribbean which makes sense as this is where the LR came from. The reason I need to know is because I want to get 3 or 4 pederson shrimp and everything I've read says that they only host in Bartholomea annulata and condylactis gigantica and I've never really cared for the condys. I'll be putting pictures on this reply and the following 2 or 3 since I've never figured out how to get more than one pic in a post at one time. Any advice on that would be appreciated also. Any help on identifying these Aiptasia would be greatly appreciated. Thanks in advance, David
