-----Question-----
Hi, i currently have a 25 litre coldwater tanks, and soon will be upgrading to a REKORD 80 tank. I have 1 comet, 1 shubunkin, 1 fantail, 2 regular goldfish & 3 white cloud minnows. After looking at my new tank in the shop, i noticed that it came with a heater. If i was to use this heater in the new tank, would my coldwater fish survive? Im not planning on adding any actual tropical fish in with the colwater ones, as i am told this would end in bloodshed!? Am i right? If however, i cannot add my coldwater fish i will then go tropical! What do you suggest??

Hey Tracey,
Your cold water fish would survive with a heater, as long as you keep the temperature around 75 degrees farenheit ((Room temperature, I'm not sure what it is in celcius. Im from the US.))
I like heaters because they alow you to set the tank at what ever temperature you want and keep it there, with out having to worry about the temperature of the room the tank is in to drop to low or get too high. Also, I would buy a thermometor, they are a good investment and you will be glad you bought one- I always find myself needing one.

You actually could get some tropical fish, but you would need to be careful.

First, the tropical fish you buy would need to be docile. I have had fish like Mollies, Platies, Guppies and swordtails live happily with comets, goldfish and fantails. I would stick to Mollies and Guppies more though, in my experience Platies and swordtails can be slightly aggressive, especially the males.

The tank temperature will need to be from 75 to 80 degrees celsius. Tropical fish need the warm water, but the warm temperature won't harm the cold water fish. With the coldwater fish, it's not nesessarily that they need to be in cold water, but that they can be in it, and warm temperatures shouldn't bother them. My goldfish actually like the warmer temperature.

I suggest after setting up your tank and having the temperature at about 75 F, raise it to 80 F and see what happens. If they seem happier, then try getting some guppies or mollies. If they act strange like they are unhappy, then drop the temp back to about 75 and consider buying more cold water fish.
You could also buy the new tank andhave that be tropical, and keep your old tank set up with your cold water fish. This can be a pain though, running two tanks can take a lot of work.

Good luck setting up your new tank! I hope everything runs smoothly!

Hey tracey,
sorry for the delay, my computer was really messed up. =[ its fixed now though.

For clown fish, you would need a salt water tank. Your coldwater tank has freshwater, like spring water, but clownfish are from coral reefs and need salt water like in the ocean. You can buy aquarium salt at pet stores.

You can also get clown fish onoline if you can't find them near you. They could do over night shipping and they normally are very careful with shipping. I'm not sure how much that would cost though, and I'm pretty sure salt water tanks are difficult to get started.

I agree though clown fish rock, and finding nemo! lol

good luck, maybe you could even run another tank for salt water fish.
Best wishes, chelsey
