There all small. The jag is about 4-5inches. Id say shes double the midas' size. The SN cat worries me cuz he eats like a horse. I think if they do hatch nd start to swim around the SN cat is going to eat all of them. Mayb the JD and Midas to.
They will hatch in a couple of days depending on when they were fertilized. I would put water from the original tank into the one you're putting them in. Temp should stay the same as it is in the original tank. I usually keep my temp around 80-82 degrees. This is some information that member Cross127 gave me to treat the fry:
Ok here is what you need to buy.
1LB of potato
a couple eggs
Hikari First Bites.
Frozen Brine shrimp as well as Brine shrimp eggs
Freeze dried Hikari Blood Worms
and a Bag of frozen peas
When you feed the potato just cook it first and plop it in the tank and within a day there should infusoria for the little fry to eat in there and after about 4 days stop feeding them that because they will no longer get enough nutrition off it but start feeding hard boiled egg yolk that is wrapped in fine mesh. I like to use panty hoes. Just shake it in the tank a little and there should be fine particles coming off. You can also feed Hikari Fist bites at this time. After they get a little size of them begin the Frozen Brine Shrimp and Blood worms. The peas are fed to control protein consumption and help digest. If you have algae in the tank do not remove it because fry love to munch on it. Especially hair algae. you should be fine though if you do this. GL on the fry.
Oh and keep your water in prestine condition to speed growth.
