Yeah most of my males have been good fathers. My channoides male held while being chased around with a net and then moved to a different tank, and my rutilans male (he counts because he mouthbroods) held when I thought he had gotten out and I stripped down their entire tank haha.
Only male I have had problems with is my strohi, but they were doing renovations in the room he was living in with lots of banging, movement and power tool usage so I think he got stressed and swallowed both times. I found a buyer for that pair though, so will only have my unimaculata once they get picked up. I don't particularly want unimaculata but they are my mum's, and the plan (for me) is that they will not be replaced when they pass.
It's such a space thing when you have the bigger mouthbrooders. Not only do you need a decent size tank to house the breeding pairs, but also even bigger tanks to grow their fry out. I much prefer my clarets. A 10 gallon tank is perfect for a group of these fish.
I have a lot of B. hendra fry at the moment. The parents were really prolific but have since stopped since I took away their film canister and they have some bigger fry in with them.
I put this photo in my journal as well, but I like how it just captures the true spirit of bettas. Squabbling over a pile of blackworms. Male is not happy (right) that female is guarding them.
