    Hi Guys , i went to go and collect some water this weekend at the Aquarium, went inside quick to use the toilet and walked past the Clown display tank , Lovely tank but 3 quaters of the fish were half dead , with a few dead ones to , my personal opinion is that the tank is hopelessly over stocked.

    Has anyone else noticed it ?

    Kind regards

    I was there a couple of years ago, and was already not very impressed by the clownfish display. Almost all the nennies were bleached and like you said, a lot of dead clowns.

    U guys dnt think it was caused by the toxins in the water? They did close up collections for a while due to toxins, an maybe they sufered in certain tanks cause of toxic water in the water changes..... They are a very big attraction an so if they dnt maintain they will loose business, so maybe they in the process of cleaning up the mess the toxins cause..... I mean I been there on more than 1 occasion an there tanks are always show class:thumbup:

    I think you might have hit the nail here, I was at the display 2 months ago and all was fine! So think the water might have had a effect on them.

    is it your first time in while there Dummies?

    Two Oceans gets this complaint an awful lot... The clowns are just a best special from generations of inbreeding... They "host" the viewport - wallowing around on it - sometimes on their side, upside down, goodness knows what. There's nothing wrong with them. I sincerely doubt any where actually dead - they just acting like a bunch of clowns.

    That tank doesn't run on a closed loop - very few of the small tanks do - so I wouldnt call the tank overstocked from a bioload point of view.

    and no - the albinos are in a smaller, separate tank.

    Um, dead-dead or just odd? I have 80 captive bred clownfish in my tank and they certainly behave strangely.

    The Two Oceans is pretty good about removing dead fish. I've never seen one on display. I've seen the clownfish in that tank and they've always behaved strangely IME (before LuckyFish). Some of them appeared egg bound (fat, scraping ovipositor).

    In general, it's not a natural display. It's good for kids, though.

    You are right Dane. I remember when JacquesB phoned me for the same reason.
    Bored ocellaris lay around a lot, especially when fed well. I have never seen a dead fish at the 2Oceans. They care more about their livestock than the majority of reefers.

    When the light goes on in the hatchery, the older broodstock pairs are laying in the pot, and I mean laying.
    The juveniles in the grow out system are laying at the bottom in front of the front screen, stacked like wood. Looks funny, like keeping dead clowns in a shelf. Sometimes 5 rows high.

    Correct, opposite from the Nemo display. In the wall where the shrimps are.

    The TwoOceans has got three different batches in the display. 11 to 12 years old, 7to 8 years old and the smaller ones, around 250 came all out of my hatchery.
    As I am not allowed to sell fish yet, I donated them to the TwoOceans. At least I musn't feed them any longer.;)

    TWO Oceans Aquarium - response

    Dear Duimpies and others

    This is effectively my first post to this forum so I will first introduce myself. My name is David Vaughan and I am responsible for Aquatic Animal Health Research at Two Oceans Aquarium in the V & A Waterfront in Cape Town. I have been involved in South African public aquaria since 1997 and I specialise in parasitic diseases of fishes.

    I was given a printout of this thread recently and thought that it would be good to present some inside information for you.

    The clownfish tank which you refer to is one of my personal favourites (that and the kelf forest). The "Nemos'" behaviour is certainly uncharactristic but I can assure you that it is not health-related or water quality related. Indeed it appears to be learned behaviour which resulted some time ago with our original batch of clownfish after they had been introduced. The large dome in the centre of the tank for public viewing was "confused" by some of these original individuals as a large transparent anemone. In the morning most of these clownfish would be found lying laterally on the surface of this dome and more and more individuals took on this bizarre behaviour. We eventually introduced some anemones thinking that this would encourage them to revert to a level of normal behaviour but with the inclusion of new batches of clownfish over time, more of them have taken to this curious behaviour. When next visiting, ask the aquarist in charge to offer them some food. They make a remarkable instant recovery to scramble for their food. Some pairs have also been removed from time to time to our lab to spawn, so in all regards our Nemos are certainly happy if somewhat confused and lazy!

    Regarding toxins and animals lost by Two Oceans Aquarium, this is not accurate. On occasion we do experience problems with incoming seawater with regards to incoming high ammonia levels or low oxygen levels but we just shut off our main pumps and circulate our exhibits on closed system. All exhibits can be maiintained this way for long periods of time and until the problem with incoming seawater has dicipated. It is on these days that we also do not offer any of our water to you or any of our members. Water quality is measured daily here and is one of the most important aquarist responsibilities.

    In any public aquarium fish do die, given a variety of variables. I am happy to report that here at Two Oceans Aquarium we have never experienced a large die-off of fishes as a result of toxins or disease for that matter and continue to function as industry leaders in Aquatic Animal Health Research and ex situ conservation.

    You are always welcome to come and chat with me (on the forum or at Two Oceans Aquarium). I am always happy to assist where I can and I hope to contribute actively.

    Regards
