Thanks buddy. I hadn't though of that. I liked how the back of the tank held the filtration. The search continues .
64l kitchen tank: 16 golden tetra.
5ft 425L: 7 blue angel fish, 30 rummie nose tetra, 20 black neon tetra, 1 longfin bristlenose plec, 2 corydoras sterbai, 2 SAE.

If you want a tank with back compartment, look at the fluval evo :)

Andy - look at the post I just did on my fluval edge tank. I upgraded the filter to an external canister made by SunSun...HBL-801. I needed to cut out a bit at the back to fit the filter and then changed to light to a Fluval Nano Plant light.

There was a link to another post from a guy who had a few Fluval Edges and he referred to the one he tried with an external filter as " the tank of death" but I think I've figured out why.

The Edge has such a small surface area that, if you dont have enough turnover at the surface, the O2 levels in the water drop DRAMATICALLY at night. It couldn't support even one fish and my shrimp even climbed out or died to get out of the water.

I 'think' I've resolved the issue by adding a spray bar on the return (the return goes about 50% to the bar and 50% to a reverse undergravel filter as the flow of the canister is 3 times that of the original filter and I needed to reduce the overall flow so the tank wasn't a washing machine).

Reason I changed the filter is it allows me to have at least 4 times the filter media than the original filter but I didnt consider the reason Fluval provide a waterfall type filter....and that was to provide enough agitation to the returning water to keep the 02 levels up.

As for a Betta in a Fluval Edge tank....I think it could work with the standard filter. They are a member of the Labyrinth fish family and usually live in water which can be low in oxygen anyway so have the ability to breath air from the surface. Have a read of these:

https://www.britannica.com/animal/labyrinth-fish

While this would help in a Fluval Edge scenario IF the oxygen levels dropped, you'd still have to maintain all other tank parameters needed for your fish choice.

Like I said, I think I've nailed my problem but I've yet to introduce fish and a Betta is one I'm considering so I'll let you know.

Cheers

Jon

Bettas need to take in air to the labyrinth organ. If the tank is full (as they should be to work as designed) then they cannot get that air. It's not just O2 in the water with any labyrinth fish. ;)

You'll be amazed at the amount of people who don't that into account. The best one, my all time favourite was a woman in World of Water in Rolvenden who said to the store assistant, "why does it need to take air, it's a fish!"

Somehow it doesn't surprise me though, did the assistant tell her why?

How would a blue dolphin moorii get on with a Betta? From what I read it's a very calm fish and not territorial unless spawning. Anyone have any experience of those?

in reality, don't mix anything with a betta.
Plus you wouldnt want a 20cm fish in with one!
I've managed it with small tetras and rasboras, but even then its a risk.

A big cichlid with different diet and water requirements.......
