I recently switched to a 10g tank with an Aquatech 5-15 filter. The output was
WAY too strong, so I used the water bottle trick.

This helped a LOT, but there's still areas where he's getting blown around pretty bad. He's always loved to hang out by his filter & heater, so despite him getting knocked around, he still goes over there.

The suction on the intake isn't that strong & he doesn't really seem to have an issue with it. Is there anything else I can do? I was thinking about getting some live plants & putting them in the areas where I see him struggling.
Help!!!
