Sexing green severums

[Sharron Marsden]

Can anyone help me sex my green severums the large one keeps chasing the smaller one around the tank they were both bought at same time
The larger one has dots on its face are these liklyl to turn to the worming pattern that iveI read males have
The smaller one I can't quite work out and seems to be a lot paler in colour

Hi and welcome to the forum

If one fish is chasing the other then they are probably both males.

The best way to get a pair (1 male & 1 female) is to buy a group of 8-10 young fish and grow them up together. Then let them pr off naturally and remove the prs as they form.
