Bedotia leucopteron (sp. "White-Fin") Eric Bodrock

This is one of the new species of Madagascar rainbowfish to be introduced to hobbyist in the US in the past year.  An active and peaceful community fish with interesting colors and markings, you'll want to take a second look at these guys!

Their overall body color is gray with an odd iridescent green cast thru out, accented with random black specks of various size and shapes.  Fins are clear with black highlights and trimmed in white.  My breeder males have grown from one and a half inches to two and a half inches in the six months that I've had them.  The females have grown from one and a half inches to two and a quarter inches in the same time period.  The males, in addition to being larger in size, also have larger and longer dorsal and anal fins.

My breeding group of five fish, two males and three females, were set up alone in a bare twenty gallon aquarium for spawning.  A sponge filter, along with regular water changes of fifty percent every ten days kept the water clean.  The pH stayed between 7.2 - 7.4, temperature in the upper seventy degrees Fahrenheit range and a TDS meter reading of 239.  Both a floating yarn mop and a sunken mop were added for them to deposit eggs into.  Diet consisted of live black worms, live baby brine shrimp, frozen bloodworms and assorted flake foods.

Within a month of setting them up, I started to find clear, 1.5 mm diameter eggs in the spawning mops.  Once a week I remove the mops, which I would guess contain somewhere around twelve to twenty eggs each, and place them into a two gallon tank for hatching.  Within a few days of pulling the mops, tiny free-swimming fry can be seen dashing about in the hatching tank.  Euglena is added as a first food at this time, about one ounce a day.  After a week, Microworms replace the Euglena and a few days after that live newly hatched baby brine shrimp is added to their diet.  I move the fry into a larger aquarium at the time they start to accept the baby brine.  Growth of the fry seems slow for the first month, but once they reach a quarter of an inch, growth rate increases. 

I have also had some success in spawning them and obtaining fry right from the breeding tank without the trouble of pulling mops.  If the breeders are left alone, tiny fry will periodically appear swimming around in the tank with them.  The adults don't seem to bother the tiny fry, but I do believe that larger fry will eat smaller fry that hatch after them.  If you elect to try this method of spawning them, make sure that the parents are well fed at all times and remove the larger fry as soon as you are able to catch them to help reduce the chance of the newly hatched ones being eaten.  The addition of a few extra spawning mops wouldn't hurt either for more spawning areas and refuge for fry if needed.
