Glass petruding from my fish anus .

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. .

I will wait a few dates and post updates . If I have too ill catch him and take a pic out of the water.. im just scared if I catch him it may do more damage . He is quite crazy when you catch him.

Day 4 still no change , the fish is still eating and attacking things as usual . I am going to wait until sunday before I attempt catching him . I may try to catch him with a ziplock container instead of a net . That may be easier and do less damage.

I haven't fed him anything but shelled pea's and i did add 1 teaspoon per gallon of aquarium salt. I have good news . I went to empty the tank to catch him with a container . I noticed the glass is gone but there is a big cut where it was . Now im emptying the 140 gallon to sift through the sand to find any glass and do an 80 % water change . Is there anything i can do to heal him up properly besides clean water and salt ? Or is that the best route.

This is definitely a refreshing breath. I found the glass he had stuck in him and removed it and found a few more pieces .. I almost cried . By far one of the best fish and pets ive had. He's not out of the woods yet but it is a start. Ive decided not to feed him anything but shelled peas for the next 5 days and hopefully he will heal up . I will post photos later once I find my camera cord and the kiddo's are in bed.
