are you talking about Exodon paradoxus? these are very beautiful tetras. i once had them in my south american tank. they did not bother the small tetras or any other medium or small size fish at all, but they kept bomb-diving my poor Semaprochilodus. i eventually had to return them to the store. tsuh yang In a message dated Sat, 14 Apr 2001 10:18:26 AM Eastern Daylight Time, YE <yenoo@home.com> writes: << If youre thinking of adding characins (tetras) as predators, look up some exodons, beautiful "regular" tetra sized hunters. Nice long sharp teeth too. :). At the lfs here, when they do have exodons, they feed them goldfish, pretty much the same size as the exodons or abit smaller. I think other predators like catfish would be nice too, but may be a little difficult to observe since most catfish are only active at night. But I still think the single dwarf pike would make a nicer addition to the tank. >> ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
