I read from other sources that the submersible heater in a aquarium tank with a RES should be well protected. Due mainly to the nature of the RES of "always wanting to destroy things". Is this true? im hiding my heater rite now behind 3 rocks against the side of the tank so that my RES cannot even touch it.
Am i being paranoid? or am i really protecting my RES? if i can take it out, so that it doesn't have to be protected by the 3 rocks, should i get heater guards?
thanks a lot!
