Swordtails & Guppies

Mollies & Platies

Here's a tank plan for you if you want livebearers. If your tank holds 20 gallons, don't have any more fish (with livebearers) than: 2 pairs of fancy guppies, 2 pairs of platies, 1 pair of black mollies, 1 trio of swordtails(2 females, 1 male), 2 cory cats, and 1 pleco. This tank plan was suggested by Barbara Taube, the person who sold me my first fish tank and my first fish.
