Great advice! This should be common knowledge because it works well and fast. Although he lost his meal, the salt did the trick. I scooped him up and gave him a strong solution out of the water, then just put him back in the tank. I've been watching him close and within 3 hours I retrieved the rubber band from the bottom of the tank. Big thanks to HondaS3000. This was a scary situation for me as this is the one fish I distinguished as special out of 300 or so. Although most of his siblings look like texas cichlids, he colored up and grew a kok. I just bought him a silver aro as a tank buddy today and was thinking to myself as the rubber band flew into the tank "these two will look nice together." A terrible case of good news bad news to the wifey when she came home. Thanks again guys.
