So I have this 1.5 or 2 Gallon cube fish tank with a little heater and small tetra whisper filter one that runs off an air pump. And I have 2 feeder guppys and one female Fancy guppy. Tryed to breed the guppys but did not work so well. Any way I saw this betta at Walmart in this little cup and really want to get it but was wondering if the guppys and bettas could live together in that small of a tank or should I not get the betta
Tank is already overstocked, and generally it's a bad idea to mix bettas and livebearers.
Heads up, I tried putting two male fancy guppies in with my betta, he tried killing them instantly. I managed to save one, but the other wasn't so lucky. However I have a friend who keeps guppies with his betta and has no problem. If you do mix guppies and bettas, make sure you have a plan B just in case.
