Can a Betta live in a six-gallon tank with mollies and a platy?

Answer 1

Yes I have done this many times, but make sure it is with fish that won't nip at it's fins. I also found they seem a little calmer with some cover so I float plants on top of the tank & they tend to hang out there.

most deffinately, many people do not know that you may also keep male and female betas with placo's (algea eater), and short fin danios, or any small fish that does not have bright colors or fancy fins. The only problem with adding fish is that your tank will become alot dirtier.Also make sure that you have no more that 1 inch of fish for each gallon: example: total length of fish= 10 inches means you need at least a 10 gallon tank which usually cost no more that $12 or $13 at the most.

but my 10 gallon aquarium costed 70$ dollars which came with a roof with a light and a charcole power filther and my betta lives with 2 fancy guppies

Answer

Yes, you can keep a male betta in a tank with mollies and platies. Just keep an eye on the fish to make sure that they are not nipping at the bettas fins. Avoid over-crowding, make sure that tank maintenance is up to par, and ensure that there is an area of the tank's surface that is calm for the betta to use for breathing.

NO! The basic rule that all successfull aquarists use is "1 inch of fish needs a minimum of 1 gallon of water". A well bred Molly will grow to around 3 or 4 inches. Platys grow to around 2 inches. So 1 molly and 1 platy will max your tiny tank out. There is insufficient room in the tank for a Betta or anything else. (The recommended size tank for a Betta is 10 gallons. (nominal) )
