And let's make it a very visible external stick-on type, so I can pass by my 20-long rainbowfish tank and notice that it's up to 90 degrees in there.
yeah, heater flaked. 100-watt Marineland Stealth... I thought these were pretty good, and it's not the only one I have, either. Lucked out, no dead fish. Haven't seen the few RCS shrimp, they're probably buried in the ferns as usual. But from now on, no moving the in-tank thermo's between tanks because I'm too cheap to buy more of them.
