Since my Hendra pair passed away (SIP little ones...), I've been thinking of getting another pair of wilds. I don't really want to get Bettas from the Coccina complex again, not because I don't like them or something, but because I don't even know what happened to my Hendras. What if it happens again? They're supposed to be the most difficult complex of wilds, don't want to risk killing any fish again! We shall not forget that they're endangered in the wild. So, I talked to my mother and explained her that there are not many wilds that can go in a 6 gallon. So she let me get a 15 gallong, 60 * 30 cm. I was thinking of getting a pair of Betta Channoides or Albimarginata, they're supposed to be one of the easiest wilds, but then... Looking at the IBC, I saw the Betta simplex. I instantly fell in love with them. The tank will look something like the tank I have for my rams, and I'll also put 3 clay pots in there, the ph will be about 7.5. Don't even have the tank yet, but that shouldn't be an issue. Now I have a question about them. Some sites write they reach 8 cm, and some others 5. What's their real size? (Just a note, nothing is gonna happen right now, after all the lfs will need a few months to get the simplex pair).
