Hello Loach Lovers,

I had got few small Gastromyzon's a year ago and they have become adults.

I believe i have Gastromyzon Viriosus and a Gastromyzon Zebrinius.

My LFS told me they have a dozen Borneo suckers coming in tomorrow. I am trying to find pairs for the ones i have, can you look at attached pictures and help me identify if they are male or females?

What is the best way to tell Gastromyzon sexes apart?

The first two pictures are Zebrinius and the last two (with a yellow tinge) is Viriosus

As I know, males may have longer and more pointed fins than females, but they are really challenging to determine.

Just want to add that males are also generally smaller and thinner than females
