Im moving my male veil tail betta from a 2.5 gallon unfiltered tank to a 10 gallon cycled tank. I am new to the fish keeping hobby so I wanted to know how to acclimate him to the 10 gallon. It is a heated tank and the 2.5 doesn't have a heater, so there is quite a temperature difference. Another thing i should mention is that I no longer have the cup that i brought him home in, or a bag to float him in. So what can i use to float him in the 10 gallon with? I've tried ziplock bags, but they don't work. They only seem to just tip over.
