ID's Please

[kramleigh]

Hi all!!

Every now and again we get this paper thin transparent 'thing' crawling along our glass. Its quite quick moving and attracts a lot attention from the fish. any ideas what this is please?

Also - have just seen this crab in a crevice in the rocks, it's about 1" and looks very menacing. Anything to worry about?

the first pic looks like a juvenile Polyclad Flatworm. they are known predators, usually corals. they should be removed.

the second pic i cant even tell theres some thing in the cave other than the red glowing eye, its impossible to ID a crab from that pic.

Looks like Flatworm to me...VERY bad!! Somewhat difficult to get rid of as well. Can't even see the Crab. If you can get a better pic or a description, we may be better able to help. One general rule of thumb is if it's a crab you didn't introduce, it's usually bad. Another rule of thumb is that if it's got black tips on it's pinchers, it's generally bad. Hope this helps.

Is it true that the Leopard Wrasse eats this type of worm?

a wrasse may eat them, but manual removal is probably best. the Leopard Wrasse is not the easiest fish to keep either.
