Trickle Filtration?

After reading over Rose's Betta guide again and watching Atlantis be whizzed through the tank, I got to thinking that even at the lowest setting my filter may be making too strong a current for him. I thought of taking an extra foam insert, cutting it to size and placing it where the spout is, like so;




The flow has been reduced very much and he's been swimming without problems through the whole tank. Will having that extra insert cause any problems? He really seems to enjoy this more, I just don't want this to mess with anything.

 

I have that same filter in my 5gal. betta tank my betta doesn't seem to be fighting the current at all and has no trouble getting anywhere he wants. I can't see that foam being a problem.

 

I haven't had any problems with those filters, sometimes julian will get pushed by the current if he swims right under it (which he does often) but otherwise he swims pretty freely in the tank.

 

BTW you really shouldn't be keeping a goldfish in a 2.5gal, they are terribly dirty fish and they need at least 10gal per fish.

 

I have HOB filters on all my tanks as well as the other filters in the tanks and they all have small pieces of filter cloth in the outlet to slow the flow. It is okay as long as it does not stop the flow.

I've got no choice at the moment, it's either in this tank or back in the bowl it was in when my mom had it. He's just waiting to go to my niece.

Atlantis was doing okay swimming through the tank, he just seemed to get caught in the current more than I was comfortable with. I'm likely going to keep it there for a week or so just until he's completely used to the tank and I'll try taking it out again.

 

I do the same thing with my filters... put filter floss in front of the water outlet. It doesn't stop the flow and it really helps reduce the current. It also extra cleans your water. As long as the water is still getting in the tank it's fine.
