Glow shark breeding

[Haymond]

I bought some fish a week ago and have them in a quarantine tank. I noticed an hour ago the two glo sharks are swirling around in the water together and looks like they are pecking at each other’s mouths. Is this breeding or aggression?

I would assume you are observing aggression. If you want to learn more, read this thoroughly: https://www.seriouslyfish.com/species/epalzeorhynchos-frenatum/

There are precious few reports of them being bred in captivity without the aid of added hormones -- a practice done in certain international fish farm facilities.

Hopefully this is the case. Today is tank cleaning day and I am going to pull out the lava rocks and rearrange the tank. Hoping this gets them through another week of quarantine until they can be moved to the big tank.
