    Default my cold water guppy experiment!

    0 Not allowed!
    So I was growing some plants outside to acclimate to brackish for my brackish tank, but I needed mosquito control and added 3 guppies( I thought they were all female). Anywho I ended up with a lot of guppies by the end of the summer.

    I took the good looking males and put them in my 30 gallon community, but what to do with the other 30 or so fish.

    Feed them to my brackish fish? I couldn't really stomach that

    Turn them into LFS? I could but every inexperienced fish keeper, soccer mom, and every other person who has no idea how to run a tank I see buying guppies. So no

    I then tried to see if they could survive southern California winter.

    Days were still hot come October and started to cool down in late November. At 65-70 degrees the guppies were still quite active and I even got another batch of babies at around 70 degree water temp.

    As nights went to around 60 and days still got to 68-70 I noticed they became sluggish in morning and night but mid day were still very active.

    December hit and I got a couple of cold spells, every day hovering between 50-60 but some nights or even 3-4 nights in a row would drop to 45 degrees and rise to like 55.

    They were very sluggish but still in the water column and still kicking!!!!

    However the fatal blow seemed to have come at a cold spell a few weeks ago with outside temperature dropping to 42 degrees for 2 nights and not much higher than 50 degrees for the day high.

    So it is sad they did not make it but I could not house them and didn't want them to die in some diseased tank.

    However I am surprised by the survivability, these are tropical fish and should be dead at 65 degrees water but I have found them survivable up to 45 degrees. Amazing!!!

    So it was either 42 degrees threshold that ended them or consistent water temp below 50 degrees.
    They did survive quite well for the few weeks when lows were around 46-48 degrees. I would conclude any tank that does not drop below 50 degrees(for the low) can house guppies year round.

    So instead you let them freeze to death. I don't see the difference between being with you or you giving them to the lfs so every inexperienced fish keeper, soccer mom, and every other person who has no idea how to run a tank could kill them. Why didn't you buy a heater for whatever it was you had them in when the nights were starting to cool down?

    When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top... Kingfisher
    Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.

    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
    Imitation is the sincerest form of flattery.
    Dear naps, sorry I hated you so much when I was a child... Love me

    I conclude that you somehow find guppys freezing to death in inappropriate conditions more palatable than them being feeders or the other options you mentioned.

    Lack of planning on your part does not constitute an emergency on my part.
    Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
    Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.

    A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.

    I can understand your logic but when the temperature was dropping into the 50's it should have been obvious they were going to die. You should have taken them inside during the cold spell.

    I understand the bit of rage here.

    I would have loved to house them but im out of room, my tanks are max stock, and my room is maxed out in terms of both weight the floor can handle and space.
