Hi!
I collect (legally) from tide pools in the indian ocean. So I get some hitchikers that are a bit unusual.
The last time I added anything was about seven weeks ago. Suddenly, ive found nudibranches - I think? - all over. uploadfromtaptalk1407653183858.jpguploadfromtaptalk1407653196373.jpg the third is too small to photograph, though it is orange.
One is brown, with little spots and protrusions. One is inchworm green with a white mantle.
They must have a food source I assume, if they have survived this long. I'd love to work out what they eat so I can provide it. I am able to go collect sponges, different algaes, etc to feed them.
Any ideas? I assume they are local, as the only alien thing s in my tank is live rock - and I'd be surprised if they'd survive the curing and transport.
They are all nocturnal, and can swim. (!)
 
I suspect the brown one is Aplysia while the green one is an Elysia. Both are essentially vegetarians. No idea about the orange one. A poor picture is better than no picture at all. Able to take one?
