Hi i'm Mark and i'm new to the forum
I was wondering if anyone here could help me. I recently purchased 4 juvenile Congo tetra's from my local fish store, I was told they were male but i'm not 100% sure. They are not currently showing any signs of coloration or fins developing, Hopefully somebody here can help me with my problem
Thanks in advance!
