Whatever sex this fish is, do not add another one. You don't want the fish to spawn in a community gank and this one especially because mutts are not very popular you wouldn't be able to get rid of surviving fry.Thank you for all your replies! Just giving more background info I always thought it was a female but never spawned so wanted to confirm. Wanted to get a partner for him/her but was never sure what sex he was so it’s been left alone
Gotcha, understoodWhatever sex this fish is, do not add another one. You don't want the fish to spawn in a community gank and this one especially because mutts are not very popular you wouldn't be able to get rid of surviving fry.
Also a singular female rarely spawns without a partner. I only know of one case.
