My friend Marcel is a gifted aquarist with a true talent for planted aquariums, aquascaping and breeding rainbow fish. He maintains two large planted tanks (180 gallon and 72 gallon) as displays, and a small nano aquarium that is his ‘experiment’… natural light, no filtration, no heat and only snails and shrimp for fauna. You will get a good look at all of them in the video. Marcel also applies the basic principles from his planted displays to his rainbow fish breeding and rearing tanks in the basement. One of the keys to his success with planted aquariums is layered substrates, which he also makes us of in his breeding tanks by planting on pots. Thank you Marcel for letting us in for a glimpse of your fish room!
This video shows all four of the Pseudomugil species I am currently keeping. This fish in this genus are also known as ‘blue eye rainbow fish’. They are all relatively small and make good community aquarium residents. Some like hard water and others need soft water, so research any species you want to get; however, I have never had any problems keeping them for long periods of time in treated tap water.
Pseudomugil are mop-spawning egg layers. The males work hard to attract females into the yarn mops where she will lay an egg or two at a time as he fertilizes them. Healthy blue eyes will spawn a few eggs every day. The eggs, depending upon species and water temperature, take 8 – 15 days to hatch. They are not too hard to raise starting with very small foods such as paramecium or powdered fry food (I like Sera micron). Once they are large enough to eat baby brine shrimp they will grow very fast. I put the juveniles in with the parents once they are half an inch long. I think that large colonies of blue eyes produce more offspring than single pairs or trios, and the interactions between the fish in the colony are a lot of fun to watch.
