Sick Fish, Need Help Please!

[Skies]

Betta moved to very small bowl for now. Had someone help with water changes! Yellow sucker fish has sucked almost all the scales offgoldfish

goldfish now swim/floats upside down, looks furry and appears bloated(could be lack of scales). If still alive tomorrow, how can I humanely end his suffering? And what can be done about the yellow sucker fish. The original tank owners don't want it, and I would like to turn it into a planted tank for my betta and maybe get him a friend or two. The heater for tank went out a year or two or so ago and never replaced it, also no aeration other than filter. I want to do a soil planted tank. Will I need heater or aeration? Never needed either for bettas. Figured I should ask since you guys will know and better to do it right than ask for help in my fish's dying days. Thanks for all your advice.

If you don't have clove oil and can't get to the store, since goldfish are cold water fish, you can scoop him up into a bowl and place him in the fridge for an hour or so, this will bring it's body temperature down and induce a hibernation like state, after which, you can place him in the freezer... but I would not wait until tomorrow, you will only prolong it's suffering, it's dying... and I'm sure in a lot of pain. The sooner the better...

Well, I would follow the advice of everyone above, it's all a bit sad just now but persevere, follow advice from this forum, these guys are good at advising, and will definitely get better. 
 
Good luck and do post updates as you go along.

Goldfish didn't make it. Betta in small bowl for now and yellow sucker fish in big stock pot with pump/filter; tank has a leak. Not sure how long I can keep him in the pot though. The original owners are out of town for labor day. Friend supposed to bring an aquarium over tonite or tomorrow. Does my betta really need a heater? I've never had one with any of them. I live in Texas, where 65ºoutside is called winter and only happens like 6or 8weeks of the year.

Yes you need a heater.  The betta needs to stay in water that is 78F min and is kept stable which is why the need for a heater.
