The thing I think about Petco fish is pretty much how I feel about puppies at pet stores.
Sure, you don't want to support the shop in that you'd like to see them either A. stop selling or B. own up to a little care, but when you fall in love, you fall in love, and it isn't that particular animals fault that it's in a crappy place...
Give it a home if you want....it probably deserves it.
I got a new dog not too long ago, from someone who was probably a 'backyard breeder', which is VERY unrecommended. I didn't really mean to, it just ended up happening. And so far, she's been awesome. I mean, how could you not love this face:
Sorry to get off topic a bit, but my point is, you want a particular fish, you find one, you should feel free to purchase said fish with a clear conscious as long as you plan to QT it and protect the pets you already have from infections it can bring in.
At least that's my 13 pence.
PS - I like the lawnmower as well, as long as you have a little bit of 'leafy green' in your aquarium. I really like the starry blenny posted above, too. Either would probably make a great addition to your tank.
