These fish are awesome. I think they are well worth setting up a brackish tank for. I haven't found it difficult at all. I got eggs from Gary (thank you sir) on January 30th and by the 3rd week of March, I had fry swimming around with the adults. That means that with a minimum 10 day incubation period they matured in just under 6 weeks. That has to be a record for rainbowfish. They eat bbs from the time they hatch, max out at just over an inch in size and the display is amazing. They are like little neon fighter jets zipping around the tank. I still haven't figured out how to get them to use the mop, but there are a dozen fry swimming with the adults so I guess it's not that big of a deal. Attached is a picture of their prefered spawning site... The sponge covering the overflow outlet...

Wow, that's really fast! Did you let the eggs hatch with the adults? They don't eat the offspring? That would be a great thing when breeding the species. A few years ago I had 10 of these... only one day. In the night they all swam in the filter through a little hole in it. None survived. Still hurts.

Yea Hans, they have at least 12 fry swimming with them now. Maybe as many as 20+. They must eat some fry when you see how many eggs they lay but some are surviving just fine. I feed them a massive amount of bbs in the morning and they eat them all day. The next morning there are usually a few still swimming when I top them up again. I think that having food in front of them at all times maybe helps prevent predation of the fry. That's the benefit of a brackish tank.... the brine shrimp don't die.

I was playing with the camera on my new phone. They are no Hans macro shots but not too shabby for a phone. ;-)
