I have a breeding pair of Electric Yellows in a 245 L community tank. The male is 10 cm and the female is 8 cm in length. The other fish included an assortment of community fish such as Tetras, Rainbows, Rams, Catfish and so on. The Electric Yellows get along all with these tank mates, however, they have done some damage and have eaten a number of my Zebra Danios, White Clouds and Celebes Rainbows. Actually I thought they jumped out and my cat found the remains and ate them. As these fish are surface fish (Zebras etc), the Male Electric Yellow went after and no doubt enjoyed his treat. The size of these fish were also small and torpedo like while the others in my tank are not. It was only when I found the Celebes Rainbows remains and spoke to my LFS did I realize that they tend to go after certain varieties of fish. Overall we enjoy their colour, their size and antics in the tank, especially at breeding time. Their size adds a dimension to the tank of predominantely medium and smaller fish. The Electric Yellows have bred four times in the past year. Each time there have been around 12 fry. I was able to rescue two broods, of which one brood of twelve are in my maternity tank growing like weeds. The others were lost due to vacation and an attempt to see if the fry would survive in the tank by themselves, which they did not. Oh yes, at the time of this writing, the male just dug his usual breeding hole and no doubt in 6 weeks will have another brood available for trading. I now net the female and isolate her in the maternity tank where she maintains them in her mouth for five weeks before spitting out. During this time she does not eat a morsel of food.
I have kept Electric Yellow labs for the better part of a year, and I have one spawning so far. They are very social animals and will dance for their supper. They should ideally be kept in groups of one male to two or more females, and can be inexpensive when bought young. The only drawback is that you may not be able to distinguish male from female at this stage. Males with have much darker black colouring on pectoral and anal fins, which females do not develop to that intensity. If you buy young, you may wish to ask your LPS if they will swap excess males for females in the future. They are mouth brooders, and females will generally hide themselves away when brooding. I don't strip the mother as many breeders do, but I do move her to a safer environment so she can release the young. They vary between very peaceful and slightly aggressive, but do seem OK with other fish (I have a bristle nose in with them who manages to keep his own).
I purchased 2 electric yellow fish from a local pet store; first time I've seen them offered. Luckily it turns out, I have a male and female. I searched dozens of sites on the net trying to find info. Some sites offered 'not so good' advice. The first batch of fry died within a week. We had stripped the mother and returned her to the community tank. This time, we set up a 75 L tank, put her in it, and 3 weeks later we saw the fry when she spit them out - over 20 of them. We are keeping her in with them until they are too big to fit in her mouth. The fry are growing fast, and she still picks them up during the day and spits them out. There are times we watch them and the fry appear to be trying to get back into her mouth...she closes her mouth tight and swims away.
