I have some questions concerning my 4 week old fry.
I have 1 fry (I’ll call him “Spot”) which appears to be 2 days ahead of the rest, developmentally. When I noticed Spot sporting some nice caudal fins, I noticed the same, in most of the other fry, 2 days later. When I noticed his anal fin, 2 days later, I noticed it on some others. Is this some kind of indicator, perhaps of a recessive gene/trait/characteristic?
Are there techniques for determining if the labyrinth organ has developed properly? I thought I would’ve noticed Spot going to the surface for air by now.
I’ve also noticed they like to gather in the hiding places I put in for spawning. I’ve left them in the tank and even added a couple “caves”. I make them by cutting small plastic trays in half – the kind that my microwave meals come in. Do you add any kind of structures to your fry tanks? Does it help to keep them off the bottom?
I’ve been “practicing” rearing fry of other species for the last 2+ years. In my “makeshift” spawn logs, I refer to each generation as G1.1, G2.1, G3.2, etc. G for generation, 3.2 would be a third generation male bred to a second generation female. I’ve noticed referrals to F1, F2, etc., spawns. Can someone point me in the right direction for proper genetic symbol usage?
Is there a term for a group of betta fry? I know livebearer spawns are referred to as “drops”.
