Its quite simple to breed cold water fish:
The main thing you need for breeding is a moss plant they are dark green and quite smelly, moss plants contain small worms in them that swim around in the tank. Its always important for the tank to be the right temperature but its not a main priority they can still breed if the temperatures not completely right. To tell the sex of the fish all you have to do is look at there tails. males have smaller tails than females. To get a simple breed of fish try mixing together a fintail fish with a common goldfish.
You can not put tropical fish in coldwayter bevause they need hot water to survive but you can put goldfish in coldwater becaue they are coldwater fish
No. Corydoras are tropical fish and do not do at all well below 70F.
salmon, cod, herring
You can buy cold water fish from your local pet store, or aquatic center.
Hiya. I have a whole heap of coldwater fish. Their names are Tamara,
What you need to look for is not particularly "freshwater" fish. What you need is Coldwater fish rather than Tropical fish. The coldwater species that may be available apart from all the different types of Goldfish. are Golden Orf, Rudd, Roach, and various catfish species too.
Broadtail Moors are in the goldfish family and coldwater fish. They are bred in China.
Yes, a betta is a tropical fish. Tropical fish all have different temperatures at which they do best at, but goldfish are coldwater fish. Coldwater fish come from from a variety of different temperatures as well, so yes there is a temperature difference. You could not keep goldfish and bettas together because of the temperature difference.
Guppies are actually tropical fish and prefer water temperatures between 72-82°F (22-28°C). They do not do well in coldwater environments as their immune system and metabolism can be negatively impacted. It's important to maintain a consistent and appropriate water temperature for guppies to thrive.
There are several species of coldwater fish but no coldwater fish are really suitable for keeping in aquaria IMO because they all belong outside in ponds. There are Blue Dace, Golden Orf, and Koi Carp and several species of catfish to name a few.
'green in greekgreen' in french=le vert greekgreen dedans.
You are doing the wrong thing to your fish. Goldfish are large growing (over 10 inches)coldwater fish and should have temperatures around 55F. Mollys and Plattys are small tropical fish (around 1.5 to 2 inches) and need a temperature of around 70F. Either your goldfish or your tropicals will be suffering. The metabolism of tropical fish is higher than that of coldwater fish. This means that the tropicals should be fed several times daily (at least 3) provided their water temperature is correct. The coldwater fish should be fed at least daily if their water temp is correct. MY advice. Separate the tropicals from the coldwater fish and do the right thing by them.
