Have you moved Perry into the new tank yet? Is it bigger? I think its fun to move them once in a while because its fun to watch them explore their new home.
For me it's the dog, two of mine are mixes, both rescues & they're great. Mutts aren't necessarily healthier or live longer. You have to be careful with pure needs because not all "breeders" breed responsibly. You gotta do research about the breed you want & the breeder you want to purchase from.
LOL. I love dogs as well. German Shepherds are great dogs. I had a Yellow Lab but sadly she got old & passed away 2 years ago so now I have small dogs & will probably stay with the smaller breeds.
Oh they come in all kinds of colors. Before I got my first one, who's almost 15 yrs old, I had only seen the fawn (creme) colored ones. My eldest is tri colored; black, tan & white.
