What contry are you from?We don't have borneensis here, we have only Chilala lopis.
A few of lopis have some stripe or pattern like RCK but not clear.
Only this fish it was difference and clearly.
Only Laos and Cambodia is where Chitala Borneensis cannot be found where Chitala Lopis occur. However both Malaysia, Thailand and Indonesia where these two species overlap. Not really have an actual clue on the species yet but it's best to take some mtDNA and compare that to Chitala lopis or Chitala Borneensis.
