Re: Angel Eggs
After the fry are free swimming, I've used a few small snails to do clean up. If your grow out tank is under a light, your slime may turn to green algae on the sides. The fry like to pick at the algae, so I leave it.
I usually siphon about a third to a half of the water each day, once they are free swimming and eating brine shrimp. About an hour or two after the afternoon feeding, once I start seeing little bulging pink bellies, I will siphon up any debrie, dead brine shrimp, etc. from the bottom and maybe clean the front pane of the tank so that I can see the fry. I usually siphon into a bucket because I know I'm going to get a few of the babies as well. That way I can fish them out of the bucket before I throw out the water. Also, I use aged water from a tank that is near the temperature of the fry tank to replace the water, especially at this time of year.
One trick I've learned is to use about 1 & 1/2 teaspoon of salt per gallon of replacement water once the fry are free swimming. The salt needs to be well mixed into the water before putting the water back in the fry tank. Brine shrimp will live longer in this slightly saline water and so there is less chance of fouling the water. I've also heard that the salt encourages the slime coating on the fry and reduces possible diseases. I picked up this trick from a member of the Killifish club, Marty Fischer. It works well on Notho and other Killifish fry.

"Been there, done that," I guess! Good to know both batches are doing well!
