A couple yrs ago, a couple of my dragons also had hookworm and coccidia, after the Albon treatment they also changed their eating habits (and also still had hookworm). Albon reduced their appetite and it messed them up for several weeks after. I ended up giving them several rounds before giving up and trying Parazap. Within a couple days of giving them parazap they were eating again. It really does help. Mine would never eat pellets until I tried the fruity ones, they scarf them.
