i saw that petco care sheet when i was looking for an aro, so i checked the place out. all of the ones i've been to had absolutely no selection and def no aros.
Mine has a decent selection at times.. mostly full of Molys and other small guys... some nice Neon Tetras. other than that.. I go agree on the care sheet thing.. just my opinion even a 180 seems kinda small for a life tank for a Aro.. but its def better than saying a 40 >.>....
Longnose Hawkfish.. hmm... I'm assuming that does have a long nose (duh on my end) but i don't remember the little guy having one.. his face was short and roundish if i remember right.. sorry i know its a bad pic.. old Katana camera phone.
One petco near my house had a 5 inch silver arowana for 30 bucks. I wanted to get it but all I had was a 29 gallon tank at the time so I passed . It was there for about 2 weeks and the owner said they removed it, so now they dont carry them anymore T_T. When I finally got a bigger tank, I had to pay 50 bucks for a 6 inch Arowana from the LFS >.<
