Watched a vid today by bioaquatix and he said he’s breed clowns as small as 3.5inches. Also heard a lot of the smaller ones are the ones doing the breeder.

Bioaquatix breeds clown loaches in a controlled environment, using hormones, so I'm not sure that one can compare that to the average breeding size in nature. Kalimantan (Indonesian Borneo) ban the export of clown loaches above 15cm/6” to protect vital brood stocks. That’s the size at which Clowns are thought to start spawning. In Sumatra, no such ban exists.

Well you figure if they can start the breeding at such a small size hormones or not then in the wild they must to right.

Not necessarily. And of course that could just be smaller males taking part, not smaller females. Typically males are smaller in stature than sexually mature females. And obviously the smaller the female, the less quantity of eggs that would be produced. You don't see any photos or vids of anyone stripping roe from a 3" clown loach.

You watched the vid that Adam posted, yes? This isn't a natural process. The hatchery workers manually strip the eggs from the female, and manually fertilize them with sperm that is milked from the males. If Bioaqutix is stating that their CL's are breeding in captivity naturally, without hormones, unless they have video documentation and I have somehow missed that over the years, I'm calling BS.

Yeah maybe males get ready early and your right you don’t see people stripping small fish. All seem over the 6inch mark. I haven’t seen them do smaller.

Still a long ways away from satisfying the export market, but this is a great start.

Musi Banyuasin Managed To Develop Botia Fish

Ornamental fish Botia (chromobotia macracanthus) successfully developed in Banyuasin, South Sumatra, in the form of cultivation technology dissemination by the Center for Research and Development of Ornamental Fish Culture (BPPBIH) Depok and Fisheries Department of Musi Banyuasin.

The success is marked by the achievement of a total production of 20,000 tail with 4-5 cm body length ranges and survival rates reached 60-65 percent ready to be exported to Europe.

Head of Fisheries Banyuasin Abdul Mukhohir said for the development of ornamental fish Botia will initiate the transfer of technology to the People’s Hatchery Unit (UPR) and create a plasma at the community level.
