About this part

The open feeding hole in the Flex lid lets dust settle on the water, tempts curious cats, and gives a jumpy betta a way out. This cover closes the hole with a small swing door. At feeding time, nudge it open with one finger, drop in the food, and it swings shut by itself.

Compatibility
  • Fits: the original Fluval Flex 9 gallon (34 L) and 15 gallon (57 L). Pick your size: the smaller door is the Flex 9.
  • Does not fit: the Fluval Flex 2.0. Its feeding door is a different shape; see our Flex 2.0 replacement doors.
Why it helps
  • One-finger swing door that closes by itself.
  • Keeps dust, cat paws and jumping fish where they belong.
  • Clicks into the feeding hole: no tools, no glue.
  • Black or white to match your tank trim.
Installation
  1. Pick the size for your tank (9 or 15 gallon).
  2. Press the cover into the feeding hole of the lid until it clicks.
  3. Push the door with one finger to check that it swings freely.

Perfect fit for my tank. I love having easy access for feeding without a gaping hole fish can jump out of.

Trap door fit perfectly. Allows easy feeding without using the lid. Which has a terrible design that drips water down the back and sides of the tank Everytime you open it. This addresses that flaw perfectly. Well done!

Didn’t know they made these! This is such a great idea. I got it because my cat likes to stick his hand in my tank. This cover fits great. I was worried it would be easy for a cat to push down and open but once it arrived that’s not the case. It’s well made and you have to push it a bit for it to open. It’s not hard to open… just not too easy for my cat haha. It’s very well made and fit perfectly in the hole on my 9 gallon tank. Highly recommend. It looks very sleek and like it was made with the tank.

Quality item that was delivered quickly. Will have some microplastics hanging on to it, so give it a sand and a wash before installing.

The build quality of the item is actually pretty good. The reason for the low amount of stars is due to the fact that I was shipped the wrong item. I ordered the opening lid for a 15g Fluval Flex and received the one for the 9g Fluval Flex. The 9g version is smaller and it does not fit correctly on the 15g. I will update my review once I have dealt with their customer service.
