When to move a tub outdoors?
I've got a 20 gallon container pond that's been nice and sheltered all winter in my shop (it had a heater, filter, light, ect.) but it's warming up and we're needing the space in the shop. I've already put the heater on a timer to get the fish used to the day/night temp shifts, and they've handled it with no problem. They also handled accidentally having the heater, filter, and light turned off for 48 hours because someone turned off a breaker and forgot to turn it back on.
The species I keep are very hardy (zebra danios and Heterandria Formosa) and have been able to handle temps in the 40's, unintentionally. I'm planning on waiting until the night temps are in the 40-50's range, but other opinions are appreciated.
