they are in a 20gal tank with 2 lemon tetras--which the angels never seem to bother, nor do they bother the angels
when i turn the light off, they seemto be fine, but i dont want to keep them in the dark!
i do notice however, that the smaller of the two keeps "pecking" at the heater
my water temp is 80
thought about going to get a piece of slate today to see if they will spawn
sure wish i knew what sex they were--and believe me i have tried every "method" suggested, and quite frankly--i dont think either one of them has a sex!

ty for any suggestions
