im not new to fishkeeping but all i've kept is goldfish, they now live in a larger tank im my room. In my small original tank im planing on housing a betta, atm i've planted it up and am waiting for it to settle before i add a betta, all the usual levels like nitrite amonia etc are 0 ph 7.8 and its a constent-ish 26 degrees C i guess this is ok for a betta, is there any thing else i need to know about them because im hoping to add one next week, this is what the tank looks like atm its getting there.
There are tons of pinned topics on bettas that are really really helpful. Some basic things to know about bettas, males are solitary and aggressive and should not be kept with other bettas, bettas require a high protein diet, and are also carnivores, while they'll tolerate vegetable based flakes if its their only choice, your best diet options are betta pellets (such as hikari betta bio-gold) supplemented with an occasional snack of frozen bloodworms. It's also a good idea to fast your betta once a week because they can get constipated easily. Bettas do best in warmer water 76-82 degrees F (not sure what that would be in celcius). Do you have a filter in your tank? If not you'll have to do frequent water changes, hmmmm thats all I can think of right now, lol. Feel free to contact me if u have any other questions
