Thanks for the reply steve. The worms are certainly not the type of nematodes that are resident on the aquarium glass etc. They are protruding from the anus of the two angels, about 1mm diameter, semi translucent / white and up to 100mm in length. Since the worms appeared yesterday, both fish have stopped eating. They dont break off in sections, but as whole lengths. Yup, bloodworm are red mosquito larvea - I generally feed frozen bloodworms ( in adition to many other frozen foods + dried foods) for maintenance and conditioning. For live food I mainly stick to white worms ( allthough I currently dont have any)/ brine shrimp (adult and newly hatched for smaller fish), however local stores stock live bloodowrm, which the fish have occasionaly recieved to add a little variety. I have never fed live tubifex,mas I am quite aware of the dangers, I stick to me gamma iraditaed frozen food. I have now stopped feeding live bloodworms. Over here "black worms" anre a form of black mosquito larvea, not Limnodrilus worms, or not that I have seen marketed in the last 17 years. What do people reccomend feeding to appisto's other than dried food? I appear to have sporadic outbreaks of disease thats hard to cure, such as these worms and the still "unknown" appisto problems, in well kept tanks with good water conditions. It is getting rather infuritaing that on one hand I can keep and breed fish at the harder end of the scale ( wild discus, choclate gouramis, wild caught corydoras etc) but appear to loose fish such as my appistos / angels through no diagnosed problems, and not much I can do about it. I may just be picking at straws, but the live blood worm is the only thing I can think of. I would dearly love some really nice appistos, after looking at some of the lesss common fish that are out there, but untill Ican find the cause of these problems.

Other than the Camallanus worms I mentioned most parasitic worms would remain strictly internal. They may be some harmless oligochaetes (white, about 1 mm long, inching along on the glass or wiggling about in the water). These worms feed on fish waste and uneaten fish food. They are common in the aquarium and are easily introduced with live plants, live foods, etc. Occasionally some may be seen on a fish, but only inadvertently and tempoarily. Often they will live happily in the filter and then be seen in other places after the filter has been cleaned or when gravel is disturbed. > You mentioned feeding live bloodworms. We usually use the name Bloodworms in reference to Midge fly larvae and buy them frozen or freeze-dried. Around here (NW U.S.) when people sell "Live Bloodworms" they are often not insect larvae at all, but aquatic worms such as Tubifex or Limnodrilus (also called blackworms). Feeding these worms can occassionally cause problems very much like those you originally described. That is why people on the list asked if you'd fed live Tubifex to your fish lately. Also as you described in your experiences, some fish are very susceptible to these gastric problems while others rarely show such signs. > Back in the seventies, when it was common to feed Tubifex to all fish and Malawi cichlids were at the height of their popularity, someone figured out that a syndrome we had named "Malawi Bloat" was related to the feeding of Tubifex. I can now remember killing many fish that way but it was an occassional thing and I don't think I would have believed you if you told me it was the worms. What would happen was that the fish would eat a lot of worms (some of them dead even) which would decay inside the fish and their intestines would fill with rapidly reproducing bacteria. Similar to food poisoning and it doesn't HAVE to be worms that are fed in order for this too happen. From there it could get into the bloodstream and overwhelm the immune system and you'd see the fish stuggling for oxygen at the end. > It could well be that you could correct your problems by changing your feeding practices. > (Not that it couldn't be something else) > -Steev > > > > > ------------------------------------------------------------------------- > This is the apistogramma mailing list, apisto@listbox.com. > For instructions on how to subscribe or unsubscribe or get help, > email apisto-request@listbox.com. > ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
