Other Comments: I've kept this species at various times during the 40 or so years that I've kept tropical fish. My early attempts involved breeding individual pairs in small 2-3 gallon tanks with very soft (rainwater) water acidified with Tetra Blackwater Tonic. I was able to produce small numbers of fry using LiquidFry for a first food. These early attempts were made with a very nice green strain, which was available in the trade 30-40 years ago. About 20 years I again worked with this species. Unfortunately, the strain that was available at this time was not the bright green strain, but one that had more muted colors. Using basically the same methodology, I was able to produce hundreds of fry. The breeders were much more prolific, and I was able to raise lots of fry (300+ from one spawn) by transferring the free-swimming fry to larger tanks (15-20 gallons) with well established populations of infusoria. More recently (2010-2011), I was able to obtain a very nice strain collected by a friend from Gabon. I've been able to produce moderate amounts of fry in specially modified 20 gallon tanks, using basically the same water conditions, but allowing the fry to reach the 'brine-shrimp' stage before removing the fry.

Fishkeeping Facts and Tips

Should I have water movement in my tank? Fish from faster flowing rivers love swimming against a current - fish from vegetation choked marshes do not. With todays box filters it is quite easy to get some good water flow for strong swimmers like Rainbowfish, whilst a spray bar attachment can completely remove this for gentler swimmers like Gouramis
