I have a fake plant in my 5 gallon to make the water current weaker (by putting it in front of the water output) for my dwarf frogs. It has different stems that seemed to flow away from each other to I used rubber bands to hold all the stems together to make 1 big thick one. Are rubber bands safe for aquariums? also my dad said that they will disintegrate into the water eventually. Is this true? If so, what can I use to hold the stems together that is safe for my tank and won't disintegrate?
