My cichlids look stressed Can someone help me

While I was washing dishes earlier my daughter pulled a chair up to my aquarium and threw her hotdog into the fish tank. By the time I finished washing dishes and noticed that there was a hot dog in my tank all the fish and frogs were tearing it to bits. Mainly the cichlids and the frogs were eating the small peices that were being ripped off by the cichlids. The cichlids do look a bit stressed, and my african clawed frogs appear to be spasming. I'm assuming that this might be do to the extremely high sodium levels in hotdogs. I was thinking that maybe if I were to put melafix in the tank it might help. Can anyone tell me if it would help at all? Are my cichlids and frogs going to die? Do you think it might just pass? I'm so very sad and I would appreciate any help or advise on this situation. I would also be grateful for any links that might help me.

Sodium is not the problem.the ammonia level that will come from the debris will kill the fish.so will the PH if it drops alarmingly. Net out every scrap of the debris.Siphon, from the botton of the tank, 50% of the water. Replace with dechlorinated water, one gallon at a time, at 10 minute intervals, so as not to further stress the fish. Add a slime producer, if you have one. Normally I would advise you to add a tsp of NON iodised salt for every 5 gallons of water. Under these circumstances.don't. There is probably enough already. (Salt is a curative & fish love it. It was, until the 1940's, the only fish medicant. Caution: the salt must be non-iodised)
