Awesome!!! Your journal is making me want to get back into breeding bettas. I seen a crown tail baby betta at petco for 1.99 and bought it! Not sure why. Then I went to petsmart and seen someone changed the lids from a normal to a crown tail female with an awesome metallic color and yeah she came home with me for 99 cents! Another week or so and I'll be able to sex the baby. What are you going to do with yours after they are grown? Mustard gas HM CT would look awesome!!!! (I'm a sucker for CT)
keep some, sell the rest.
i like CTs too. my last spawn was black orchid CTs. but breeding an HM to a CT will just give you combtails. not enough ray branching or webbing to be an HM, not long enough ray extensions/webbng reductions to be a CT, and the crowning will likely be uneven (some parts of the finnage heavily crowned, others almost totally smooth). though with some selective breeding you could produce halfsuns, but this is not easy. i thought about trying to make a half sun line but gave up on that.
mine always die right after free swimming. never fails. im pretty sure its a temp thing. im betting they get to much cool air when i go to feed.
thats odd. what do you feed? thats about the time that they need food they can/will eat fast or they starve.
if you have a heater, its not a temp issue. water holds temp very well, and they arent breathing air yet. also, i dont use full lids on my fry tanks and dont loose fry to "cold air".
I use to breed them in a car battery, once free swimming through em in a 25g water drum and feed em hard boil egg yolk back in Dominican Republic.
here for some reason it's a bit tougher to keep em alive when young
thats an interesting tank!
im guessing you kept them outside and gave em all natural insect larvae for food. sure they loved that.
its not too hard here, just you have to simulate their natural environment, while the dominican is probably similar enough that you can just leave em outside.
