Filter Too Strong?

[Jayladd]

I have a fluval U2 in a 75litre tank. It is currently on the 2nd "plant setting" which is suppose to give an even gentle flow. Is this fine for my betta fish? I know they like a gentle flow. You can see a current in the water. Maybe I should take a video to show you?

A video would help. It's impossible to say yes or no without seeing a vid, only you can make that decision, if it looks like he's struggling against the flow alot of the time, it's possible that it's too strong, but it's good if theres a current in the tank (just not too strong)

Most of my fish are current cravers, so I always place filters in corners firing along a long side of the tank, geting clockwise or anti-clockwise water movement. Besides being in "mode b", have you tried placing the filter vertically in the middle of a short side, aiming its current to hit the middle of the opposite short side? This ought to prevent a "washing machine" current and disperse energy left and right when it hits that glass.

Thanks, will take a video and upload it tomorrow!

Good idea, stupidly didn't think of this, will give it a go tomorrow!

Aye mate, you want to create as little flow as possible for a betta

As suggested above, position the filter to decrease flow around the tank. That way you still get the benefit of higher filtration, without decreasing the actual flow of the filter itself

You've got a very pretty boy there who looks to be coping perfectly well in your tank. In my, very limited, experience, bettas are a lot more adaptable than some make them out to be. Sure, a betta who has been in a very low flow previously may initially struggle with more current but if increased gradually they can adapt very well. I've got my betta in a 180l tank with a tetratec ex1200 filter and he struts around like he owns the place
I did notice that your boy has a few rips in his tail. Make sure there's nothing he can catch his fins on in the tank and do frequent (daily or second daily) water changes and he'll heal up really quickly. Often within a week or two.
