I am getting ready to head back to texas from missouri...a 14 hour drive. On the way up here, I had all the fry in a 2 gallon jug but in the 2 weeks since I have been here with them in the 38 they have grown quite a bit. I have been doing some research and getting several different answers on jarring fry. I know it isn't absolutely necessary until they start showing aggression, but I am wondering when it is POSSIBLE. I am thinnking they would be happer making the trip at least if they were in seperate jars not to mention easier to move. The jars would be kept plenty warm I am just wondering if 5-6 weeks old is too soon for them to all be top breathing. I have jarred the biggest of the older fry..they hatched out on oct 8th...and he is doing great. Cn I jar the rest for the trip? If so, would I need to put them back in the growout tank when I get it set back up or can they be left jarred with daily water changes?
