The Least Killifish, Heterandria formosa is a small, livebearing fish that originates from North America. It is from the same family as Guppies and Mollys. This is the smallest fish found in North America, and one of the smallest fish in the world.
My experience with this fish started because I found the colony behavior of the fish very interesting. At the local fish store, The Fish Place, they had a colony that contained many different aged specimens all living in the same tank. The larger fish didn’t seem to bother the smaller, and the fish sort of hovered in groups, and didn’t really school. A second reason for me to want these fish was to see if I could spawn the fish and turn them in for points at my local fish club. I purchased a pair of fish from the LFS, and took them home.

This article is a continuation of the previous post, “Breeding Discus – Symphysodon aequifasciatus – part 1.”
After three failed attempts, my new pair of discus have had a successful spawn. The eggs were laid on or around June 19st, 2012. The fry were all free swimming on June 26th, 2012 (Age = Day 1). Just as some others have noted, it often takes new pairs a few tries to get it right, and my pair succeeded on their fourth try.
The fish actually spawned after they had wigglers in the tank, but few to none fry survived from that spawn. Continue reading Breeding Discus – Symphysodon aequifasciatus – part 2
For many, discus fish are considered the king of the aquarium due to their unique coloration, size, and shape. This South American Cichlid originates from the Amazon River basin, but most aquarium species are selectively bred for color variations by fellow aquarists and fish farms.
For many years now, discus have been part of my collection, but due to space constraints, I could not attempt to breed the species. In a way, my current breeding pair was an accidental pairing. While I set up my new fish room, three large adult discus fish were sharing a 75G tank. Two fish were recently acquired at an auction. Since I was unsure of their age, and they were of a smaller size, they were placed into a 55G community tank for growth before adding them to the rest of the group in the 75G tank.

Hygrophila sp. ‘Bold’ was acquired through trading with a fellow aquarists on Aquatic Plant Central. Continue reading Flowering Report – Hygrophila sp. ‘Bold’
