Hello everyone, After years of lurking out on usenet and a few months on the list, it's time to throw my hat into the fray. I have a single female M. altispinosa in a 20 gallon regular tank. She's been in there for close to 2 years now (don't ask me why I didn't buy the whole group from the dealer-they were likely wild-caught specimens!), and has as company several corydoras and two tetras which I can only identify as Hyphessobrycon sp. They were sold to me as "Columbian Red and Blue tetras" and have the same general body plan as Hyphessobrycon erithrostigma. The color in these fish is lovely: deep red fins and a deep neon blue running the length of the body in the dorsal area. The tetras are about 5cm total length and are without a doubt the most aggressive tetras I've ever kept--they can really give the altispinosa a run for her money at feeding time. My questions are as follows --can anyone identify these tetras (I can't find them in Baensch or Axelrod), and are they appropriate company for the altispinosa? They've been in the tank for about 2 months, and she's been much more active in their company, so my instinct says they are fine; I'm concerned about potential future negative aspects of this grouping. Tank parameters are as follows (and are mostly uniform through all the tanks in my house, thanks to the wonderful buffering capacity of Chicago's water supply-heh): pH approximately 7.6, Hardness 170-180 ppm, ammonia and nitrates unreadable. The temperature has dropped to its "winter" setting of 77-79ºF. [Are these conditions appropriate for the altispinosa as well? She's never shown any visible signs of stress and has great color, so again, my instinct says yes.] Whew, that's enough of my long-windedness for now. Thanks for any input you can provide.
