hoping someone can look at the pics of the gills in the photo and tell me what causes them to die this way. ive had a few problems in the past keeping gills alive in my bait tank, and they usually die in this fashion. they get stiff as a board and their mouths and eyes are all "bugged out". i had some leftover bait (1-doz) from a trip a couple days ago and brought them home, and put into a 5 gallon bucket of water after i added some of those blue crystals that are supposed to remove the chlorine and all the other bad stuff. they were fine yesterday, had them in the basement with an aquarium bubbler and a lid on them to keep it dark, but all were dead today after coming back from getting a bunch more for tomorrow. the smaller gills looked just like the rock bass when i pulled them out, but after setting in the garden for a while they assumed their current look. there were no blemishes, red marks, and they were still really slimy too. it almost looks like they went into shock....? i'd like to find out what the problem is before i set up my bait tank this year.
