last week, my nerodia fasciata ate a few danios. anyway, one of them was swallowed backwards (tail first). now, its very lethargic and wont eat. it is also hanging out with its mouth open at times. im wondering if it maybe scraped up its stomache on the backwards danio. ive also read that it could be a resperitory illness but, im thinking that the backwards eaten fish is the culprit. although, i think a few of them had some form of mouthrot as their mouths were kind of eaten away.
any input or ideas would be greatly appreciated.
