I purchased 3 Mexican Beaded's last July . I have them all in a 150 gallon/wide tank . My temps are good but I have had some regurgitate probs lately . One of my beaded's is in bad shape . His front legs won't move . I met one of the Doc's from the University Of Tn. at a local pet shop . He told me to buy some liquid calcium & electrolyte & vitamin d3 . He gave him a dose today but I have never had this problem . The other two are doing great . Any advice will be appreciated . My temps are 90 h & 78 low .
