I wouldn't normally name my fish, but my little sister enjoys naming any animal, and she very astutedly (is that a word?) pointed out that my one DP in particular has a potbelly and that he is, indeed, a pufferfish, and thus the name "Potpuffer" was born from her mind. Of course, the implications of the term are those which a seven year old is oblivious to; however, I proceeded to name the other two DPs "Crackwhore" and "Junkie". I want to give the brigs snail in there (as well as the 10 others on their way) a french name, but I have yet to look up a list.
My GSP doesn't have a name yet, but I am thinking Wilbur because he IS a pig.
