Hi guys,
I have had to travel into Europe; Belgium, Netherlands, Germany in order to obtain line bred specimens, but not eggs not many if any will send eggs. I am currently in the process of moving house, but I do breed these fish on a small scale rotational basis. So Later I will have a few to sell on.
MA Crowland (nr Peterborough) did actually have M.douboulayi "Kangaroo Creek" some months ago, but at £60/pair. I believe these fish were actually the real deal, looking at their colour, body form. Have to say this particular store appears to have had some good looking rainbows even if they could not always give the level of history you might want to verify the lines. MA does have an Indonesian supplier, but again details arent often forthcoming. They also get fish occasionally from hobbyists. I would say the standard has improved alot in the last few years.
Still if you are mad like me, I prefer to go to Europe. lol
There are some good breeders in the USA, but they arent much use for the UK. Also there are a lot of bad breeders in the USA and alot of the rainbows from Florida fish farms are not pure, apparently. As mentioned with G.Wanamensis it is often a hybrid. Aquabid has a few rogues.
if you see great rainbows in the shop, get them on those merits if you like them, they dont have to be pure lines, but if you breed them and pass them on that is where the issues can arise.
