A bit of an oddity here, but Wildwoods in Enfield had a few of these shy fellows on sale. The official name given is Distichodus affinis ‘Gold’ which does toss a bit of a spanner in the works because I’ve never seen an affinis with red eyes — which these fish have.
D. affinis is pretty common now, and you’ve probably seen some if you visit a few different stores. They’re in that ‘slightly too big’ category for a lot of tanks, reaching about 20cm, and being thickset with it, so they tend to linger on sale for a while.
They’re also hungry for their greens. I’ve seen guys make the mistake of putting them into planted tanks, and immediately their blank faces and soulless eyes make a beeline for the foliage, which they strip like locusts.
Still, they’re hardy and tolerant to a range of water chemistries, and get them in a big enough tank with the right crowd (similar sized cats and cichlids in a community, usually, or better still an African tank with Congo tetra, Polypterids and Synodontis) and they fit in just great.
Interesting fact — gold is just one of many colour morphs, which may eventually turn out to be separate species.
