Ceramic resistors would be fine small high wattage resistors are easy to find as eric said youd need a potting compound between the ceramic heater and the plaster outter casing generating the heat isnt the problem however you need to also detect the heat level the resistors is giving off so that it can be safely varried to avoid cooking the fish. Professor walter lewin talks about a misconception people have that the energy going through a wire to a resistor is in the form of kinetic energy of electrons.

This heat dissipation in the lattice called joule heating is the source of power dissipation in a resistor.

Resistors create heat. Creating heat with resistors. He proves this cannot be so as follows. Heater resistors are used whenever an electronic device needs to generate heat for some reason.
I am trying to create a cheap and small heating element capable of reaching temperatures of at least 260 degrees c. The results were a bit variable. They are designed as a special type of power resistor to provide a reliable and controllable source of heat.
The current density is j ia vne where v is the drift velocity or average velocity. Is there such thing as a cheap resistor capable of reaching these temperatures for extremely long periods of time without degrading. I am considering using a resistor.
A heating resistor can produce convective heat meaning it heats up the surrounding air or radiant heat. At any given instant electrons have a certain probability of scattering inelastically off of the metallic lattice imparting some of their energy to the lattice as kinetic energy ie. By running the whole 24 ohm string at 12v it passes half an amp 500ma and dissipates 6w of heat evenly over the glass surface.
