Hi all, I have a small EBJD (about 1.5 - 2 in). I've had him for about a month that. He has always been very hearty, eats well and not very shy. For the past 4 days or so he has taken to hiding at the back of the tank up high or down low in the corner. He doesn't look any different. Every now and then he looks like he is trying to spit something out. He wants to eat and takes it into his mouth but then spits it out only to try and eat it again. Water parameters are nitrite - 0, ammonia - 0, nitrate - 5 ppm. My weekly water change is tomorrow. It almost seems like he has something stuck in his throat. Not sure what to do for the little guy. Any/all help is appreciated!
