Looking lovely Mark. How long you had them? How big have they grown? My red-head tapajo's only recently started to put some weight on, but I think thats mainly because the SD's were hogging all the food, now they've gone, everyone's getting bigger lol
Nice fish , i have two and they look exactly the same, supposadly they will look even better when they're fully grown (mine are around 4inch).
When i first got mine i wasn't over keen on the fish , basically went to a very well respected fish shop and the guy told me they'd be worth it and they are. I paid £6 each for mine so cheap too.
cheers i cant remember exactly how long ive ad them but its at least 3 to 4 months . they are about 6 inches at the moment. they have probably grown an inch or so in length, most of the growth has been the body filling out and fins developing
