Almost Yunnanilus sp. ‘rosy’, but not

The 10 Yunnanilus loaches that I bought from Welsworld turned out to be Y. brevis, not Y. sp. ‘rosy’. The mistake is easy to make because the juvenile Y. brevis have very similar colouration to adult Y. sp. ‘rosy’ and I was not able to view the fish before collecting them. I have emailed the seller explaining the mistake and asking whether they are able to swap the loaches for the correct species. If not, I should be able to return the fish as they are not what I ordered.

Y. brevis grow to double the size of Y. sp. rosy and come from Inle Lake, so would be more suited to a 90×30×30 biotope with Danio erythromicron.

Yunnanilus sp. ‘rosy’ are here (well, almost!)

I picked up the 10 Yunnanilus sp. ‘rosy’ today from a drop-shipper, so since I was not able to observe them and they are almost certainly wild, they are not in the quarantine aquarium for the next 4-6 weeks. The water the loaches came out of was:

  • KH: 9.5 ° (170 ppm)
  • GH: 19 ° (340 ppm)
  • ammonia: 0.25 ppm
  • nitrite: 0 ppm
  • nitrate: 40 ppm
  • pH: 8.2

And, after acclimatisation, they have gone into:

  • KH: 7 ° (125 ppm)
  • GH: 19 ° (340 ppm)
  • ammonia: 0 ppm
  • nitrite: 0 ppm
  • nitrate: 20 ppm
  • pH: 7.8

I put down the ammonia in the water they came with down to the water being of dechlorinated chloraminated water… I think I just made up a word :-S
