The Puffer Forum

Hi,


I have 2 GSPs in a 55g tank. Today was hot, so per usual I put some frozen drinking water bottles in their tank to cool down the temperature. After the frozen water bottles melted, I retrieved the bottles from the tank as I usually did.
Not long after that, I noticed a slight numbing sensation on the tips of my fingers. So far the numbing sensation hasn't gone away and it's been over an hour. I suspect that my GSPs may have released some toxins into the tank a few days ago when they aggressively fought for the ghost shrimp and accidentally bit into each other many times. Maybe they released the toxin as a defense mechanism? Has anyone experienced this before, or can explain what might be the cause of my fingers numbing?

puffers don't release toxins.

As PP said puffers don't release toxins. Wild puffer contain tetradoxin internally but this is build up for their diet in the wild and to the extent of my knowledge puffers in captivity do not contain this. This reaction is normal with fish tanks, it is just a sensitivity to the bacteria in the tank. Just use long gloves when working in your tank in the future.
