Absolutely I have a female betta the only time when it bothers her is when she swims under the filter wish with the cover pushes her DOWN for the people that say it pushes them around but it was an easy fix I put cloth I stitched up over it or you could use a rubber band and some sort of thin fabric :)

Dear Emerson, I can't think of any reason to worry about danger to small fish getting sucked up by the filter. It does come with a screen to prevent small things from being sucked up into the filter. Hope that helps, Scott

Personally I think it may be too much for that size tank. It would filter just fine and do a great job, my only reservation would be current. It would be pretty turbulent in there and the intake might suck in some fish in a heavily stocked tank.

By itself I don't believe it's suitable because it has a strong filter, however if you do what I did it's suitable, I have two FLUVAL tanks with a betta each , and I have no problems, both are cycled and work well. What I did was I took a black filter sponge about two inches square ( you can by them at a fish store , you don't need to cut from the ones that come with the tank) and I pocked a whole in it , about an inch through ( not all the way through) then i inserted the tip of the white tube that is connected to the filter, I tied the tube to the back side grid tank ( wher the biological media is located ) It has helped slow down the flow and my bettas are happy and thriving.

In this tank, I do about a half-tank change once a month for my betta and it works fine. I have a snail in there that helps keep up with the algae and a moss ball to clean the water, too. There's not an actual filter in this one, just an air stone that I haven't needed to change.

No, it is not adjustable. You could slow down the flow by stuffing extra filter materials or partly blocking the output. It would be too much for a betta in a small tank, like a 5G. You might be able to use it in a 10G, specially if you lift the spray bar above the water level -- more aeration, less current. But if you have a smaller tank for your betta (like most owners), this would not be your first choice of filters.

The filter should be below the tank, as it works best as a gravitational suction system - but you could probably have it alongside the tank provided it is below the water level.

The water cannot come out of the filter as fast as the faucet, due to the filtering element. I found it to be ok, but not if you are in a big hurry all the time.

I'm using it for my 125 gal - 6 ft long, turtle tank. I have one Eastern River Cooter about 6-7 inches long. This filter is doing a pretty good job keeping the water clean. I think that the intake is not strong enough to pull in everything on the bottom from all areas of the tank though. I had the intake on the far right side of the tank, and the bottom of the tank on that side looked pretty clean, but the left side not so much. So after cleaning the bottom on the left side, I moved the intake to the left to try to clean up more of the bottom. I guess I'll have to alternative right and left to get all the waste across the bottom. I'm using it for my 125 gal - 6 ft long, turtle tank. I have one Eastern River Cooter about 6-7 inches long.

Yes. My tank is a bit smaller (maybe 2.5 g) and it keeps the water a steady temperature for my Betta.

I have a beta, an algae eater, and previously snails. I did end up buying a different filter.

No, the filter won't be able to pull the water up into the filter box. You may want to look into getting a Whisper in tank filter. They're made for turtle tanks.

I used this Finnex for a 20 gallon freshwater fish tank. It was fine at first, but mine did not last very long though. There are Tetra filters at places like Walmart, too, that may be a better choice.

you can change the current strength on the back of the filter. I set it to medium and my betta has no problem swimming all over

i know many people say it wouldnt work not enough room but 2 or 3 guppies- as long as water changes are done weekly would do ok .. they actually like current more than bettas .. the filter is very easily adjusted ..

I wouldn't use this for anything other than 1 betta. It's too small and doesn't have a filter.

I'm not sure because I returned mine after my fish got pulled thru & stuck in the waterfall feature. The water flow even on the lowest setting is way to strong for Bettas
