Looking for a new home for my two puffers. Had them when they were tiny but now they are just way too big for my little tank. In the process of moving so upsizing is not an option right now. Porcupine is about 4 inches and GSP is about 2 inches. Both get along and eat very well. Free to a nice home where these two will be happy. Text me a pic of your setup. 619-792-4954 Johnny...
