Toxic effects usually cause lethargic behavior. they basically just start acting sick. More serious toxins could cause seizures or convulsions.
Other signs of distress would be a
black beard. That's almost always seen when they are getting hit hard by a toxin.
At this point, it being almost an hour, I'd say you can calm down a bite more (I know its hard) as long as hes acting normal and has no
black beard.
If he drinks in the
bath you could try to give him a
bath so he can have some water. Make sure he has at least an hour after the
bath under the lights to dry off before bed.
I'm sorry if I alarmed you at first. I just wanted to get you the details you needed for worst case scenario incase he was really acting sick! I'm so glad he isnt!
