I have to say at this point I'm pretty happy with the way the tanks are set up. Turns out one of the male guppies left a gift before being eaten; found some fry in the guppy tank yesterday--caught two to add to the fry tank (5 total). Moved a larger baby out into the main tank and everyone getting along famously.
There are just 3 female gups & an oto in the 10~~like to get a couple more females and a male. I'd like to add a few more zebra danios to the bigger tank, don't think I'll add any more swords except maybe another female. Corys are good. Swords don't harass them anymore but the do follow them around sometimes 'cause they know if there is food the corys will find it then they try to snitch it away.
Yeah getting rid of the comet was the smart thing to do.
10: Harlequin Raspboras, Otos, CAE
