I have two freshwater tanks. One is a 10 gallon with a Dwarf flame gourami (male), 1 guppy (male), I glofish (sex unknown), 1 Red tailed shark (sex unknown), 1 serpea tetra ( sex Unknown), and 1 Chinese algae eater (sex unknown) and one Trapdoor snail (sex unknown). The other tank Is a 30 gallon with 12 Pristella tetras (both sexes), 5 Neon tetras (both sexes), 1 spotted corydoras (female), 4 albino corydoras (both sexes), 4 kulhi loaches (sexes unknown), 2 Dojo loaches (sexes unknown), 1 Betta (male), 1 bristle nose pleco (sex unknown), 2 clown plecos (sexes unknown), 1 Chinese algae eater (sex unknown), 2 African Dwarf Frogs ( sexes unknown), 1 bamboo shrimp (sex unknown), and 1 Trapdoor snail (sex unknown). This tank is a bit over crowded but is well established and I clean and change it waters ( about 30% each time) once a week. Also I have read that plecos (even different species) don;t get along well together. However the three I have seem to get along fine. I have not had any problems out of either tank with these fish. Both tanks are well planted with the 30 gallon also containing two large pieces of driftwood for the plecos. Both tanks also have several caves and hiding places fforall the fish that want or need them. These are all tropical fish so I keep their water temps at around 74-78 degrees and feed all of them once a day. Everyone but the bottom feeders (corydoras, loaches, plecos) I feed tropical flakes. the bottom feeders I feed sinking shrimp pellets. the frogs I feed sinking frog pellets. All get blood worms as well. Hope this helps!
