Hey guys. I am looking for some advice on my EBJD. He or She is only about 1 3/4 inches long and has been very healthy up to this point. It shares a tank with a companion that's approximately the same size. They have both been very healthy up until today. When I came in this morning, I noticed that the smaller of the two has some white stringy poop. That's the first sign of alarm for me. I looked at the fish closely and don't see any white spots so I don't think it's ich. Also, the tank mate is fine and doesn't appear to be picking on this one fish. In fact, they are very affectionate to one another. This fish didn't eat this morning which really concerns me. They are fed a healthy diet of Spirulina Flake Food with occasional BBS as a treat. Would you remove the fish from the tank and/or isolate it? I'm just not sure what to do. The tank is maintained very well. I do small water changes twice weekly. The substrate is pool filter sand and I have a Fluval C3 HOB filter which does a nice job at keeping everything crystal clear. They're in a 20 gallon tank which should be plenty of room for them right now. Thanks so much for taking the time to read this and I certainly appreciate any advice you might have. ~Melissa~
