I've been searching for some livestock around Jeffreys bay, but specifically st Francis Bay. I've only been here for a day and found 2 of these brittle stars.

Does anybody know if these are good or bad?

I also saw this nudibranch which I left, but I would still like an ID if anyone knows what it is.



My book doesn't show any of them or what they eat.

Does someone know of nice snorkeling/collecting spots or tidal pools around J bay and do you see tropicals here?

Fanie,

Brittle stars are good to have in your tank. They normally come in as hitchhikers on LR and multiply rather rapidly in a well established system.
They form part of the CUC and feed on algae & detritus in the tank. In other words no need to feed them.
Just note that there are some legal implications in collecting animals from the wild.;)

Insofar as the Nudibranch is concerned: I would tread carefully. Most are not reef tank safe and tend to fair poorly in our tanks.
Almost impossible to ID the nudibranch from the photo, but IMO I would leave it alone.

Just some thoughts....

Hi thanks for the reply.
I have a post office permit, but it's good that you asked. I usually leave nudi's because I know of their specialised diets( just curious if their are any locals you could keep in your tank:tt2:).
I am mostly just worried that the brittle might eat my corals or fish as I know some do that.

I have not seen many tropical things in the water, but I haven't gone snorkeling yet. Does anyone know of some nice spots or even if there are nice stuff for a tank here?

Jeffreys Bay water is too cold for our tanks. They will live but not strive. Cold water rock pool critters can take warm water for short periods of time, until the next high tide.

Must admit it doe have a nice reddish color to it.

I will try the star, but not take anything else from Jeffreys bay waters. I am going to Port Elizabeth tomorrow. I see people collect butterflies and other tropicals there. Will the invertebrates in PE still be too cold water for our tanks?

I'm on the south coast of Durban, it's really sad to see how many people actually catch the fish in the rock pools not knowing what they are actually doing. I managed to save a Convict Tang from a guy that wanted to go show his wife the pretty fish he caught
