Or like:
"You have too many species of plant"

"Nice moss you got growing there"...even though it's algae

Here's another one-

Whenever my girlfriend is over and she finds me checking on the fish, she says: "If only I were a fish [so you could pay more attenton to me]!"

Other annoying comments-

Mom: "How much money did you spend on that?"

Friends-
"Are you going to eat those shrimp once they grow bigger?"
"Why do you keep fish, fish are boring."
