Pardon my cynicism, but there's a difference between ichthyologists and a bunch of programmers reading sci.bio If anybody really can tell me whatever the resolution was with genus Apistogramma, or what happened to genus Roloffia I'd be thrilled all to hell and gone. -- "Words of wisdom Lloyd, words of wisdom" richard@gryphon.CTS.COM rutgers!marque!gryphon!richard

Yup, i really don't know if you could call me one, but I'm just finishing up my thesis (in undergrad work) in Biology....my thesis was doing a behavioral study of the process of acclimation of clownfish (anemonefish) to anemones. The whole study was a bit involved, dealt with a lot of background research with previous experiments, and actually was a good deal of fun. I'd be happy to chat about it, if people want to hear more... bryan sabol fishman at reed

Some time ago there was a company that breed clowns ( I think its aquarium systems, the people who make instant ocean) but were unsuccessful at making money at it. It is easy as you say to breed clowns and some other fish but very expensive to rear the young. The right foods are difficult to come by in a large commercial environment. (The same pet shop owner has a pair of goby mandarins that spawn monthy in the store, but the eggs never hatch or something) So, strangely enough, it costs more to rear the young than go out and catch the little buggers. I suppose it cant be that hard to catch clowns, after all they just run to an anemone where a diver can get both an anemone and the clown(s) for the price of one! -- Ken Dalka (Bell Labs) ihnp4!ihlpg!dalka IE 2F-518 (312) 416-7437

It's no harder to grow marine rotifers than fresh water rotifers. >(The same pet shop owner has a pair of goby mandarins that spawn monthy >in the store, but the eggs never hatch or something) So, strangely enough, >it costs more to rear the young than go out and catch the little buggers. >I suppose it cant be that hard to catch clowns, after all they just run >to an anemone where a diver can get both an anemone and the clown(s) >for the price of one! Divers. Right. The reason marine fish are so cheap is they pay third world people sub slave wages to drug the reefs by throwing cyanide in the water when they then scoop up the stunned fish and ship'em. Ask your local dealer if he GUARENTEES his marine fish wern't captured with drugs. Of all the ads I've seen, only a very few state their fish were captured without drugs. Drugged fish has a very small chance of surviving more than 6 mos. Fish drugged with cyanide will have a greeish, grainy, deteriorated liver, while healty fishes liver will be the color of "normal" liver. -- "Words of wisdom Lloyd, words of wisdom" richard@gryphon.CTS.COM rutgers!marque!gryphon!richard

Ok, a guy called, I think, Peter Davies was suposed to have revises genus apistogramma (south american dwarf cichlids) in the late seventies, early eighties. Any clue as to wheather this happened ?

This couldn't be doing much good for the survival of these species or the ecological balance of our planet (so what else is new?). When you consider that some species (most African cichlids, to take a freshwater example) are endemic to one small region of the earth (often a single lake), and there can't be that many of them, it's a shame that they are caught and imported in such large numbers rather than bred. Of course, one still needs to catch some to breed initially, but this should be restricted to a few licensed biologists or ichthyologists. -- Ashwin.
