Ok, long story made relatively short: I got 2 'borneo suckers' about 3 months ago. I knew nothing about them, but since have been doing loads of research on them, particularly Gastromyzon because the 2 I have seem to be Gastromyzon (ocellatus and ctenocephalus.)
The problem is, whenever I go into fish stores they just insist that these fish are 'Borneo Suckers' or 'Butterfly Loaches' and I feel quite rude when I disagree. For example, today I was told by the stock taker of a specialist fish store that 'all the ones with red tails are female, and ones with blue tails are male, regardless of whether they are stripy or dotty.'
Now seeing as I'm only 17, and I only began to learn (via the internet! Which isn't renowned for it's reliability

On a side note, there was a loach in there that looked like a ctenocephalus (in that it had a dotty/speckled pattern throughout) but had a red tail like that of an ocellatus, instead of the stripes that I thought were normal for ctenos. Does anybody have a suggestion to what this species could be? Or is it possible they are hybridising?
Please please answer, I hate feeling unsure whenever I speak to the shop owners...
