So I upgraded Paarth to a 10 gallon (plan to house 2 ADF's with him once they're got and QTed) and is loving it right now - exploring all over the place and everything.
I noticed that the current of my Tetra Whisper Internal Power filter (for 10-30 gallons) was a little strong for him and he kept hanging around it. So, using the sponge I bought to shield my filter cartridge to prolong its life, I cut a piece and tied it with a rubber band around the filter.
My only concern is about the rubber band. Do these things give off any sort of chemicals? It sits in the water, so I was worried. Is there a better method of attaching?
