I'll attach some cucumber to a rock when i get home
I was thinking along the lines of something small and school-y like danios or something.
I used to have a 15g tank that I kept at work with a few Mollys and they had babies all the time. I just hung a betta tank inside the other tank at the top and scooped babies in that as they were born. It was really neat to see them grow and stuff, but I am not sure I have enough free time to tend to babies.
I've always liked rainbow fish, but I read that they can get bigger than my tank would handle. Maybe a couple Dwarf gouramis? If you have suggestions for some nice-termpered warm water fish that are colourful-ish, that'd be swell.
