One of my two clowns (the smaller one) has had white, stringy poop for the past few days, and I just wanted to ask if this is an indicator of something that I should be paying more attention to. Both of them are captive bred, and I did an observational quarantine for three weeks before adding them to my display (they are the only fish in there at the moment), and they both ate, and continue to eat normally, with no weird behavior. Both have been in my display for two weeks now. They get a variety of frozen mysis, pellets, and flake food (and I will soon be adding nori to their diet as well), and there are no signs of abnormal breathing and the small one just swims normally (i.e. no periods of exhaustion). Should I be waiting for changes in behavior before I assume anything bad is going on? My display tank parameters are all normal as well, with 0.04 ppm ammonia, 0 nitrite, and hovering around 15 ppm nitrate, with RODI water I use for mixing saltwater. I also see some darker spots on the inside of the small one's body, not sure if that is also a sign of anything.
