I have two warnings for those of you who have Fluval FX6 canister filters. The first is the intake screen is slightly concave on the side that faces the glass and is held away from the glass by the suction cups that attach to posts. This allows just enough room for smaller fish (In my case 15 gram ryukins) to get trapped. The second is something very basic but highly important. After cleaning the filter I accidentally reattached the canister with the input and output tubes reversed. It resulted in 5 of my precious rukins being sucked into the output down into the impeller where they were ground up. I suggest you do not use the suction cups with the intake and be very careful not to reverse the input and output hoses. Other than that I really do love my Fluval FX6. It's completely silent and can handle whatever I through at it.
Good fish keeping,
Glenn
