thanks for the reply, you should get more neons, they look great when they swim in a school, have your chery barbs started to breed yet, my males have gone bright red, that shows that they are ready to breed.
I'm not nitromax but I can tell you about glass catfish - I orriginaly got three, with in 12 hours one was dead, another looked as though it was about to die (took it back to LFS) and the third is still living great! I guess you have to get the right ones =)
Edit: They also like a strong current and spend literally their whole life swimming againsed it.
