well as yall know i am a fan of the dirted tank. i dirted my 30 gallon with my green sunfish in it and was planning to plant it once i got good lighting. that tank has no heater so room temp dictates it. it's been a bit chilly. well i heated it up and well........ It triggered a spawning response. he been fine for a year without digging but all the sudden he decided to dig a nest. dirt EVERYWHERE it should not have been. I had to rip it all down and clean out the tank fill it and put him back in. i'm going to have to clean out the sand and dirt later on cause it's going to be way to cold the rest of the weekend to do it. live and learn i guess lol
