Help! I have a 20 inch long catfish (Leiarius pictus). Tonight he ate a floating glass thermometer that was in his 220 galllon tank. I watched him swallow it....I figured he would spit it out BUT he hasnt and its been a few hours. This is no longer in his mouth, I see a long bump under his belly. Has anyone ever had this happen? Will (can) the fish spit it out after some time (this will not pass the other way!). Thanks and wish us luck!!
