Tropical Full
20 gallon tank of tropical fish start over most of the most active, full color?
I have a 20 gallon tank and I had done during about 8 months and now I want to swich to the tropical fish in cold water fish, I realized that gold fish are not enough for me to want your suggestions on what you should get in my local pet stores want fish that are inexpensive that require little space to live but they live in the community and are fun and colorful, or I can GIV some tips on what I wats out for because I never had tropical fish in cold water only
Guppies, Dwarf Gouramis, Cardinal tetras, rasboras Harlequin Cory catfish, and Neon Tetras Betta fish are all beautiful, colorful, suitable for the size of your tank. Obviously they cannot all live together, to mix and match a little, and www.aqadvisor.com use to help.
