I BELIEVE YOUR FISH HAVE ICH, WATCH THEM CLOSELY WHEN THE LIGHTS ARE TURNED ON AND YOU WILL WEE SALT SPOTS ON THEM...MY TANG AND EMPEROR SNAPPER GOT ICH AND I DROPPED "COPPER SAFE" ACCORDING TO INTRUCTIONS, THEN IN 3 DAYS THEY STOPPED BUMPING AND HITTING THE SAND...IT WAS A CUTE DANCE, NO? ANYWAY, YOUR FISH IS NOT RETARDED BUT YOU NEED TO RESPECT THEM MORE...WOULDN'T YOU DANCE AROUND TOO IF YOU HAD ICH??? HEY, ALSOS THEY TELL ME THAT ADDING "PRO-TECH" WILL BE GOOD BECAUSE IT GIVES THEM SLIME WHICH KEEPS THEM FROM GETTING DISEASES...GOOD LUCK, HOPE IS WAS OF HELP...I'M JUST LEARNING TOO!!! PATTIE
