Just wanted to remind you that there are alot of people on here with Arows and ask away any questions you may have.. Arows are a great fish but theres quite a bit to know about taking care of them and since you have entered into the monster world owning one of the these..you can learn alot by asking.. or read up on all the Arow threads.. An Arow is a very special fish... so hope you enjoy him as much as we do.. And we are here to help..
yea thats an aro but that is one heck of a deformed back.... They are powerful jumpers. I tried to move mine to a bigger tank and uh....it kinda jumped outta the tank and onto my couch and then onto my floor. Be very cautious if you intend on moving it. Good Luck with it.
P.S. My silver is still alive!! hehe
