I bought 2 half moon male betta fish they are in a 60 liter divided tank I also bought online another betta listed as metalic silver male betta as my intention was to get a aqua one trio 32 liter tank that can hold 3 betta's. I bought it yesterday and decided to setup today as one betta was in 12 liter tank for the night. The aqua one measures 55 cm long 25 cm high 25 cm depth for me too small not enough swimming space so I put the metalic betta into my 127 lt tank that had a young female convict and 2 otto catfish . The convict started stalking the betta and the betta started faliring up so I moved the convict I am left with the betta and 2 otto catfish what can I put in there with the batta the tank measures 81 cm long 46 cm high and 46 cm depth. I had a female betta in a community tank for years but would like to know if this metalic silver betta is a male.
