how to create (strong) current

[mikemou]

Hi, I'm thinking to add glass catfish to my 55 gal and I read it somewhere it's best to 'have strong current' for them to swim against to asimilate their original environment and make them happy. I have a Penguin 330 which creates current/water flow, the lower the water level the stronger, but is it good enough? What else could be useful to create current? Thanks!

You could get a small power head from your lfs. They are usually used to run undergravel filters or other filters, but you could just attach it to the inside of the tank to create current. Some even have flow adjustment so you can adjust it to your needs.
