My 2 gold dojo loaches always hang out between the heater and the glass.
It never comes on. I'm worried about when winter gets here when it will turn on.
In case anyone says anything, I know they like cool temperatures but they can live in warmer temperatures too, as long as they're not set at discus levels. I've had these guys for almost 2 years, always kept them around the mid-70's and they've been excellent.
Also these pics remind me I need to remove my black background sheet and carefully wipe it. I really didn't notice those water stains until I took these shots and looked at them.
