adventuresofttelracs asked: Hey I got a baby betta fish at a pet store and im just wondering how long you think it will be before it is full grown? Maybe you are familiar with the baby betta fish they sell at petsmart and maybe know about how old they are at purchase. Also right now I am keeping it in a pretty small tank since it is small but do you think it will need a heater once I get a bigger tank???
Okay so this is a really tough question— I’m gonna offer an unasked for opinion first, they shouldn’t sell baby bettas at stores and people probably shouldn’t buy them. They’re tiny and cute and sweet and also very hard to take care of, imo.
That being said! I think a small tank is a good idea because your little betta is very tiny after all. Most importantly for him though is that it isn’t too deep. He’s very small, but he still needs to be able to swim to the surface and get air. HOWEVER This brings up a bit of a conundrum- If you want your baby to grow up to be big and strong, he needs optimal conditions, which includes warm enough water. He’s still tropical after all! How to keep the water warm, with such a small space, I am really not sure. :/ Hannah had a baby betta for at least a month, he was darling and actually was doing pretty well in his super tiny tank with bi-weekly water changes and no heater. But he still passed away.
To get a guesstimate on how old he is— I don’t really know when they take in baby bettas to sell. My best suggestion would be to google things like betta breeding and betta fry and look at the photos breeders post of their fry, because I have seen quite a few breeders posting progression images of their fry as they grow up, and you might be able to compare and contrast.
SINCE I haven’t really been able to give you that much information (I’m sorry D:) I highly suggest you run over to tumblr user wellpoopstoyou, previously known as gokillthehipster. She is very good with bettas and might be able to help you out more!
