Bugs Help Identify : Friend or Foe

[butrflynlambie]

Hi Everyone -

It looks like I have some bug activity lately. I think I have a bloom of some kind. I am in need of help identifying the good/bad and course of action.

I think this is a baby snail and... something alien

Flatworm? Good bad?

The bug on the right is a munnid isopod. Great critter to have. They also make great snacks for your fish

This appears to be an acoel flatworm. Not terrible to have, unsightly mostly. Wrasse will eat them.

the first picture on the left looks like a stomatella snail, which i have in my clean up crew. have you recently gotten algae or corals from anyone without dipping?

 

[butrflynlambie]

not sure... couldn't get a good picture of it. Pretty transulent.

I initially thought these were sponges. But I think they are eggs of some kind.

Any thoughts?

Acoel- they are more of a nuisance than danger. There generally isn't just one. Siphon them as you see them Unless they become large in number. As a safeguard, you can add a sis lined wrasse, melanurus or lunare wrasse (lunare being smallest of the two). If you can find one, blue velvet nudibranch is excellent.
Last resort - Flatworm stop

I did about four months ago. Most likely I introduced them from that purchase. Nothing has been noticeable until recently.

the best part of having a glass box to look at them is that we can watch all the time keep an eye out but i like having stomatellas in the tank. some people get certain wrasses and they will certainly kill every single one of those with time. probably like a six line wrasse or similar

Thank you! I was concerned it would be the flat worm eggs. I have heard of mass outbreaks of them.
