Something in the filter box "stung" me- what was it?
I put my right hand in the filter box to clean the media. It felt itchy, then I removed my hand and it burned for the next 2 hrs. Benadryl topical cream didn't help it much. A few red blotches were visible.
I put my left hand in the main tank and nothing happened.
I'm concerned because I've noticed some platties and rams flashing, but I see no signs of ich nor hydra nor anything else that could bother them.
Any speculations on what caused the irritation on my hand? First time I've ever hurt myself cleaning a tank! Ouch! Felt like jellyfish sting- can hydra sting people that badly?
