Guppy's Mouth Stuck Open and Gills Expanded
What in the world happened? My 2 month old fry's mouth is stuck in the open position and its gills are expanded and it can't shut its mouth. I noticed this yesterday. This morning its still like that. I fed the fish this morning and the poor fry is swimming around frantically trying to eat and its not able to suck in any food. Its belly is looking like its getting smaller as its not able to eat. I know this sounds really depressing and I probably can't do anything about it because the little thing is fast and so small. Any ideas as to why this happened? Maybe it's jaw got locked open like TMJ?
