    1 - Henrica ornata starfis (looks like the middleone could be a different species - are its arms more flatterned on the bottom than the other two). Wouldnt chance it in a reeftank. THey should eat detritus but also eat sponges. Keeping it fed in a tak might be difficult.

    2 - does it ever open?

    3 - cushion stars. Perfeclty fine in a reeftank
    the snails wit hthe round shells (Oxystele spp.) will be fine in yuor tank. THey jut have a tendency to climb out.
    THe ones with the pointed shelles are Burnupena spp. They feed on dead or dying animals. Would not trust them near a reef tank.

    4 - Cape urchin (Parechinus angulosus). Might be ok in the elevated tem of your tank. Will eat algae. Not sure how destructive it would be in a tank.

    Be careful with local stuff bud, an urchins are bulldozers in a reef tank, tend to knock corals over. Also the local stuff is very sensitive to the elevated temp, remember warm for them is 15-16degrees(I think!).

    cushion stars

    The cushion stars will acclimatize fine to the reef tank the rest are not so fond of the warmth.

    Ive got cushion stars in my tank. They fine and will adjust to the temp,the urchins wont survive. I also wouldnt put local stuff in tank. Temp way too warm for them. The round shells (Oxystele spp) snails are o.k. Mine has never climbed out. But I have seen it happen. Thats about as far as i will go adding cold water stuff.

    Thanks for the replies guys. The orange thing (2) looks like a sea slug it has tentacles.

    I'll keep a careful eye on the ones i'm adding.

    @ deadmeat : are you back in town, how is the studies going ?

    I would think there snails with the round shells adjust well to temperutures as they always chilling on top of the rocks to catch a TAN :p

    Ok

    1.) They dont like warm water.So they will die!

    2.)I dont know what this is...sorry.

    3.)The pin cusion stars are cool.Just regularly check on them as they DO climb out.
    I dont know those snails, and RiaanP had a good article with RE to those/or snail that looks like those, and why they should never be introduced to your tank.

    4.)Good for algae but they will topple your rocks over and get lodged in between your rock work and leave a mess behind when they ditch their spines once in awhile.

    add the cushions stars and leave the rest in the ocean. You dont want stuff dying in your tank. rather buy the stuff thats meant to live in tropical waters. Rather be safe than sorry.

    The oxystele snails are great.
    Its a big misconceptioon that everything in cape town waters lives only in freezing water. The surface temp of false bay (especially Gordons bay) can reach 20 degrees. Plus the creatures you have collected live in the inter tidal zone, where rock pools regularly heat up to temp well above what we keep our tanks at (never mind the salinity, nutrient swings etc).
    Im not saying everything you find in cape town will be fine, but some of the things will be. Just now what you collecting and how to care for it.

    Thanks, I will return this.

    Thats why I thought it would be a good a idea to put up this thread, to get a better understanding. :)

    If you can find glass shrimp they can take the warmer water. I had loads of them in the tank for a long time then started feeding them to my mantis shrimp. If you do manage to find some give us a shout please I'd like to get more for the mantis.

    I have two of the local urchins in my tank (the purple ones), I got them when they were tiny, they have been in my tank from the beginning (and from previous tank), and have even survived a hectic heatwave.
    They moult regularly, say once every couple of weeks, and they have never been destructive.

    ps. Mostly nocturnal.
    The acclimatising is the NB part, it takes a couple of hours of dripping.

    I remember catching glass shrimp when I was a kid, I haven't seen a single one since, I have even visited the rock pools in Muizenberg where I used to catch them, but no luck :(

    Could you please PM me a location in Hermanus, I would love to get a pair.
    I have more crustaceans in my tank than fish at the moment.
