1fish2fish, I can't wait for them to start coloring up also. It will very interesting to see how many take after their father.
beat2020, I do 90% water changes every other day, and add aquarium salt with each water change. I started running the sponge filter once I removed Brick. Water changes used to take me well over an hour, because I use a turkey baster then place the used water in a clear container and look for any fry I may have accidentally sucked up. Now it only takes me 30-40 min due to their size.
They are starting to recognize me now and it's a great feeling when they all swim to the front of the tank looking for food. Here is a picture of their current set up. I will move them to a 20 gallon long shortly.
