My beardie is currently underweight at 16" 189g. I expect him to put on weight once I get his superworms next week. I want to get him reptaid as I suspect he may have slight amount of coccidia which has increased a bit due to moving stress(slightly watery poop). The vets around here are not very experienced with reptiles so I would prefer to try something like reptaid first and then get a fecal done as I don't want to put him on meds if he only has a minor amount. The problem is that I know he should weigh more than 250g, but since his last owner did not feed him very much he does not weigh enough for the Reptaid XL. I'm afraid if I get the standard reptaid he will have outgrown it by the time it gets here in the mail. Can I get the XL and just water it down if he does not weigh enough?
