Explain your emergency situation in detail.
Woke up this morning and one of my fish is bleeding. Both other fish are absolutely fine and injured/ill fish is swimming around normally (potentially slightly slower, but otherwise fine). Not sure what happened. Tested the water and everything looks fine. It is possible he got stuck on something (he likes squeezing between the filter and the back glass, and the heater, so maybe he got stuck behind one or between the sponge filter and the flowerpot I have as a cave). There are also some pebbles and decor in the tank that he may have whacked. Tank also has a kind of brown algae on it, mostly on the bottom.

Tank got ich about 3 weeks ago after adding the ryukin (quarantine was a bust after another fish needed to be put into solitary for attacking and biting at its tank mates) and was treated with pisces multicure. Carbon filter has since been put back in. Can't really see any signs of ich on any fish, but may be hard to see. I don't currently have a hospital tank available due to the fish in solitary (he's getting a pond come summer).

He's hard to photograph, so tried video, and still not perfect. Video linked: New video by Catherine Cook
Quick update- I have fed them and he is eating normally (catching pallets mid sink)


it probably got cut by some ornament, it happened to my golden barb about a year ago, i added melafix every day and he was fine after a week.
