my arowana just ate something not edible.

Question
Hi. I hope you're doing ok. I just have a question regarding my arowana. I was treating him with melafix, when all of a sudden the plastic seal of the bottle went into the aquarium. The arowana was eating it and spitting it out. However, when i got the net to get the seal, it was already gone. I'm not sure if the arowana ate it. but it's gone..probably he did. I just want to know, if he's gonna be ok. will the plastic seal come out through the anus? what are the symptoms that it is in his stomach. It's been 24 hours, and he's still swimming and eating ok.Im scared.

Your answer to my question is very much appreciated. Thank you.

Answer
Wow! I haven't heard of a fish swallowing a plastic seal. Well if it has been 24 hours and they are still acting the same i'm sure your fish will be alright. Fish digestive sytems are very quick. They should be pooping about an hour after they eat. Worst case your fish gets constipated. In this case you will have to feed it cooked mushed peas without the skins. this cleans out their system. You have nothing to be worried about.
