Most of the vocabulary I direct towards fishes in my care is not widely accepted on a family forum.
I curse at fishes such as Emperor tetra's that pull on the hairs of my arms while I am working in the tank, or.. I curse at fishes such as Green Terror, that can deliver painful bite, and enjoy's displacing a gallon or two of water whenever he is bored .
I also curse at pleco's in driftwood tank that refuse to let go of the wood when I remove all of it for gravel vaccuming, and force me to manually remove them with very real chance of painful prick from their spines/pectoral fins.
But I love all of them, and the tanks bring me Loooong moment's of serenity.
