I was recently (30 days) given a surprise gift of a small (2.5 gal Aqueon mini-bow) tank and bettas...along with plastic plants.
I'm probably going to dispense of the plastic plants for live ones, but I would also like to add some decorative touches....but what materials can't I place in the tank. It would be obvious that certain metals would corrode and probably "poison" the fish...but can I use any plastic, ceramic, porcelain, etc? Do I have to worry about certain paints chipping or corroding of decorations?
How about wood (would it rot)? or polished wood?
I just want to get a good idea of safe materials that I can use.
