once i run out of food what can i feed them… a list would be nice, i plan on raising them in a small tank for the first 2 weeks and then put them in a 30gl tank will they die from culture shock?? the big one is full of tap water i’m putting sand at the bottom tonight any additional info would be nice to tips on breeding them i plan on getting blue lights to make it look cool 
thank you should i put algae pellets in the water for them to eat??
Can I dump a bunch of Triops into a fry tank? Would I have to remove the larger ones? I think theyre strictly algae/pellet eaters but I dont want the bigger ones getting interested in my little fry.
My story:
The fry I started out with are the fry from the breeding of my two bettas. This was my first time and i was WAY in over my head. I didnt have the ability to go to the store and buy things like microworms so I grew insuforia for them but I dont really think they ate it seeing as how there are three Betta’s left from a rather large group.
I was about to clean out the tank when I noticed there were three of them, a month old approximately, and probably smaller than they would normally be.
Ive recently gotten the three into a container so that I can keep an eye on them and It’d hit me pretty hard if these three die.
They dont/wont/havnt eaten the crushed flake food that I read they should be consuming by now soo.. What do i do?
