Does the Tetra hang on the side or suction to the inside of the tank?Skavatar said:I have a Fluval U3 and three Tetra Whisper 20i. they do what they're supposed to.
you can mod the Tetra media, polyfill in the bottom and ceramics on top.
it has an adjustable clip that hangs on the rI'm of the tank. I believe you can use the suction cups only. I'll have to look when I get home.Newbubbleguppies said:Does the Tetra hang on the side or suction to the inside of the tank?
