Ok, after a fatal mistake by me and my heater (see other thread) I've decided to try again with L-183's. This time I am trying two. I am hoping to go male and female (everything I've read about them says a pair does fine in a 15 gallon) but they're juvies, so your guess is as good as mine. If I don't wind up male female, one will eventually be moved to the 29, and the other will remain in the 10 as they rarely get over 4 inches. I'll then try again for a breeding group. This time more then ever I need any advice and support you can give. I'm bound and determined not to mess this up again, so any advice, suggestions, or complements are greatly appreciated. (also... To the mods, I can't access the main forum page on mobile ATM, so if somebody could move this thread to the appropriate place, it'd be greatly appreciated!)
