Hi all Regarding the Congo tetras I'd agree with Randy. My P. taeniatus "Moliwe", still being quite small, seem to have no prob with the big fish, even at feeding time. My very shy Ch. guntheri managed just fine when I had them in there as well. If tetras is a must, the number of choices is limited. Hemigrammopetersius. caudalis is an excellent one. I haven't tried the Neolebias species so no comment. If tankmates, in general, is the question, I'd turn to killies. The Lampeyes, which someone already mentioned, are the African equivalent of smaller, schooling tetras. The Procatopus-species are generally harder to keep end breed than the Aplocheilichthys, as well as harder to come by. They are very cool and a good match. Smaller Epiplatys and Aphyosemion work as well. I have had Epiplatys with SA and WA dwarfs without any problems. Certain species of Epiplatys may be inappropriate (generally the larger ones) because they're predators. I've had Ep. chaperi, dageti, grahami, lamottei and singa with great success (roloffi with no success...). They hang out just below the surface and are good dithers for really shy dwarfs (and they are easy to keep and breed!!). Aphyosemions are extremely colourful killies, mid water level swimmers. Many of the smaller species will work just fine. They have more colour and are more lively than the Epiplatys. Aph gabunense, striatum, bivittatum, australe should work fine, If the tank is big enough, why not a few Epiplatys at the top and a school of H. caudalis for the middle??? //Fredrik - -- Fredrik.Ljungberg@saab.se Saab Ab Flutter and Loads Department voice +46 13 18 54 60, fax +46 13 18 33 63
