Recently I bought my son a betta fish and, thinking I was doing the right thing, bought him the biggest 'fighter tank' (2.4 litres) at the store and a heater. After doing some reading I realised this isn't right so went back to the drawing board.
I now have for him a 12 litre tank with a filter, a rock with holes for hiding, silk plants and water with betta conditioner drops. I haven't moved him yet as the instructions say to have the filter running for 5-7 days before adding the fish so he's still in the horrible tiny tank
he does seem happy enough though. Very friendly little guy.
The heater I have was specifically for the small tank, and is 5 watt. I get the feeling I am going to be advised to buy a new heater???? The 12L tank which he has not yet been transferred into is 71F with no heater (I'm in a warm area) but I do realise they are tropical fish and do need to be kept warm.
Anyway, I'm nervous about moving him as cycling, nitrogen, etc is still a bit daunting for me and he looks so healthy in his small tank. Does the 12L (3 gallon) setup mentioned above sound OK to move him into?
