I ordered 4 fish from an online vendor which arrived this morning, and unfortunately 2 of the 4 bags leaked. One was down to about 1/2 cup remaining, but the butterfly fish in in was only about 1 inch long, and seems to be doing okay in the quarantine tank so far. The other was down to less than 1/4 cup, with a 2 inch Flame Angelfish in it. I acted as fast as I could, got enough water in there for him to swim at least, and then acclimated to tank. Needless to say, he's not doing well right now - still alive but swimming partially on its side, sticking towards the top of water by where the HOB filter dumps circulating water on top of him. Very likely his gills got ammonia burn from the low amount of water. I'm going to be shocked if he is alive in the morning. Any ideas as to anything I can do to try to help him?
