Butterfly Piping

[BC15]

I’m at a loss for what to do, he was fine when I fed my tank 2 hours ago, I’ve tested and water parameters are normal and flow seems to be fine. Please give suggestions asap

Sorry when I googled it that was the term I saw, he was breathing really rapidly. Unfortunately he did pass overnight though
