Switching Tanks

[scrage]

So I ended up with a fantail goldfish in a ten gallon(dumb stepbrother), and after being unable to obtain a bigger tank with the money I have, I have decided to do some switching. My tank that I've had is a 29gal tank, it has a betta, 9 neon tetras, and 5 corys. I'm considering switching the betta over to the ten gallon and well... if I can anything else that will fit. So my questions are

- My 29gallon has a heater, and it seems to switch on and off randomly to maintain temperature. Does it do this on a timer of sorts or does it detect the temperature of the water? Will a heater meant for a larger tank work in a smaller one?

- I am aware I will be getting rid of most my fish for the switch, but I was wondering if there are ANY fish that I will be able to keep with my betta? I've grown quite attached to my corys...

It senses the temperature. Because of the wattage it wont be what it actually says on the heater. You just have to do it by your thermometer. Keep it on the low side and wait a few hours and check on it, if its too low turn it up a bit and do the same thing. Does the ten gallon not have a heater?

What type of cories are they?

Green.

Then unfortunately a 10g would not be big enough Are they THESE or THESE? Both get too big but still always good to know. Or maybe it's neither, sorry am not familiar with green cories.
 
If you can find them though they might be able to be kept with the goldfish (temperature wise).
I am not sure if they are safe with the goldie though, I think I read a thread about one trying to eat a cory before and they both died. Perhaps someone with more goldfish experience would be more helpful.

Goldfish really should be in a pond. They are coldwater fish and will have a shorter lifespan in tropical water.

I don't have a pond. I have a 29gal tank. I can't even get rid of the fish because I'm in a weird joint custody with my stepbrother and he wants to keep it,

A single fancy IIRC would be fine in a 29g. At least that's what I'm putting in mine.
I don't think she's putting a heater in it and that is why I was trying to figure out if her cories would be okay at the same temps since she really would like to keep them.

1. The goldies will do fine with a heater, i keep my fanicies in a heated tank
 
2. Your heater has a thermostat, this is what turns the heater off (when set temp is reached) and on (when tank temp drops)
 
3. The larger heater will be fine in a smaller tank, it just will not have to work as hard to keep the smaller tank at the set temperature.
 
4. The cories are not suitable to be kept in the 10gal. Nor will the Neons
 
5. Keeping the cories in with the goldfish is not a desirable combination, goldfish belong with goldfish, not due to temps, but due to other potential issues.

Ahh okay, sorry for the suggestion then! Thanks so much Alasse
