Went to school this morning, noticed a couple of fry dead... Started kind of panicking, didn't have time for WC... One neon tetra was gasping at the bottom of the tank, upside down. Panic mode for rest of day. Come home, and to my absolute HORROR... I see all of my fish dead, dead as stone. Except for 2 neon tetras sitting there, just kinda chillin, one gasping for air at bottom? They all have kind of frayed edges, and I was originally treating for ich... I added 2 tsp of salt (mixed with water first) yesterday, and raised temp directly from 75-81 (not directly, had to switch heaters, so I guess it took some time.) that was yesterday. Now, I have a 10 gallon tank, with 15 dead fish, one dying, and 2 that I do NOT want to lose!!! What should I do?!!?!!?!?! Their bodies seem kinda opaque if that matters... no one really replied to my other post when I needed it most, now, I just want to save my fish ;( x(
