2 nights ago my 10-gallon aquarium cracked/leaked and lost its water. My fish tank is at my parent's house while I am away at college, so I was not around when this happened. My mom came into the room at around midnight to find the tank very low on water and the lights in the tank flickering since the water had gotten into the power strip. My dad came in and simply put the tank outside so that the rest of the water didn't leak onto the carpet, leaving the fish in the tank.... not exactly sure why... Anyway the next morning he texted me and told me what happened. He assumed all the fish were dead since he had let them outside in the 57 degree cold with very little to no water. I asked my mom to go through the sand in the tank and look for live fish. She found my clown pleco, 3 corydoras, 4 kuhli loaches, and my 4 shrimp to be alive, while some others were not so lucky. She put them into a clean bucket with some of my aquatic plants and put water into the bucket. She also put the heater into the bucket. Everyone seemed fine for about a day but the kuhli loaches are now floating/sitting on leaves near the surface and breathing heavily. I eventually figured out that the heater was not completely submerged into the water, meaning it wouldn't operate properly, allowing the water to get around 67 degrees or so for a period of about 12 hours. The heater is now properly submerged and working, keeping the water at about 77 degrees. The loaches are still around the top and don't look good. She is bringing all my fish to me this evening. Are there any recommendations to help my fish recover?
