Am I Right?

[fishstick]

Am I right that pic 1 is an aptasia, and that pic 2 is a flatworm?

Perhaps it is my computer screen, but yes, it does look like aptasia...but also somewhat like a zoanthid. If you were to poke at it with something (probably other than your finger), does it sort of suck itself up into the rock, or just curl up like it looks to be in the photo? If it sucks itself up, then I would almost certainly say aptasia, if not, zoanthid or something similar.

The second photo is hard to see other than it being a small yellow/orange dot becuase it is so small.

Yes, it does go back into the rock very quickly when touched with a stick so I'm afraid it is an aptasia. Strange my peppermints have ignored it. I have found that the second pic is a flatworm so shall have to deal with that as well. A BAD day... but thanks for reply.

Flatworms are easy IMO . A smaller wrasse, or pseudochromis will happily eat flatworms. Also, although I don't reccomend them, if you try the first two and fail, many mandarin gobies also eat flatworms.

try your best at natural methods, chemical methods, although effective, cause the flatworms to secrete a toxic substance that can nuke your tank.

Thanks all for the help. Although I have only 35 litres, my water tests are good enough to get a small wrass to deal with the flatworms.
I must tell someone.. today I caught a massive (4") bristleworm in my homemade trap. I took it back to my lfs and it disappeared into their sandbed. I don't mind the small ones as I think the wrass will eat those too but 4" in a 35l was gross.

4" is nothing

Yuk. So would a small wrass eat a 4" bristleworm? Please say yes as I think there is another one same size.

im not sure a wrasse would eat bristleworm, flatworm they do eat tho. an arrowhead crab will eat bristleworm, although as long as they arent in enormous numbers they are beneficial as they stir the sandbed up

 

[shibby]

i believe 6 line wrasses like bristleworms. i think..

 

[k.o.d]

Bristleworms perform an important function of stirring the sand bed up and clearing detritus/uneaten food.

Would prefer to have them than not

In theory yes, problem is the bristleworms really only come out at night when the wrasses are hiding/sleeping. So in practice it doesnt happen.
