The Jack Dempsey Fry are now 18 day old and Bo already found a new home for several of them.  He is giving 5 to one of his co-workers.

They are too small right now so she has to wait until they get a little bigger.

I found some interesting facts about the Jack Dempsey Fry. The speed at which the Jack Dempsey fry  grow depends on a number of factors, the most important of which are the amount of fish food they eat and can digest, the cleanliness of the water and the physical size of the aquarium in which they are housed.

Generally, it is believed that a faster growth rate is achieved by feeding frequently,  at least several times a day with easily digestible fish foods, changing at least 50 percent of the water every day or every other day, and housing the fry in as large an aquarium as possible, keeping in mind the ability to maintain some density of fish food that allows the fry to feed without having to expend a lot of energy swimming around looking for it. source and more reading on how to care for them.

Bo will have to move the mother Jack Dempsey in about 2 weeks.

    • Hi truels, we need to move the mother by next week, otherwise she will eat her young fry. I started to count, but they moved so fast that I lost count. 🙂
