A few days ago some glass fell into my tank . I thought I removed it all but one of my paratilapia seems to have a shard petruding from its anus .... im not sure at this moment if it ate it or caught it in the substrate. Any suggestions would be helpful I am really lost at this point . It is my favorite fish and im not sure if I should catch it and see if I can remove it or try to let it heal and push itself out . "Kiwi" is not really affected by it . It is eating normal and protecting its corner like it always has been . Should I mess with the fish or leave it alone. I added a teaspoon of aquarium salt per gallon. and the paratilapia is not bleeding, not bloated and has been like this for two days. any suggestions on what I should do would be really helpful. It is really really hard to take a picture of this fish since it is completely black ( polleni) and I have black substrate .. with a black backround.... Kiwi really blends in very well. .
