There s no law that says you can t. An ideal setup for a betta is a 5 gallon tank with a heater and a very gentle filtration system.
In a 2 5 gallon tank it is difficult though not impossible to keep the water at a consistent temperature because the volume is so small.
Betta fish and catfish in same tank. Instead we recommend keeping betta fish with species that shoal and look to keep them in a group of at least 5. This makes picking on the same fish impossible as they are all tightly packed into a shoal. This is not a coincidence.
Your glass catfish and betta will both be grateful. Sure just make sure the catfish isn t so large that it will eat the betta. But there are some species of fish that can cohabitate with bettas in a community tank.
The siamese fighting fish or betta is a beautiful solitary creature that gets quite nippy with other fish. A small tank won t work for glass catfish as it does for your betta. Corydoras need a ph between 7 0 7 8 and bettas need a ph of 7.
Plus he is no bigger than a inch long. The aggression is not as severe as when they are in the wild unless the breeding season is near. But if you care about the welfare and health of your fish please don t do that.
However female betta fish are willing to share the same environment. As you can see corydoras catfish and bettas make great tank mates. I was down at the creek today and found this little fish struggling in mud that i found out is a baby catfish so i brought him home.
Betta fish are known for their ability to be very aggressive. Males bettas are especially territorial in the company of other males which is why they cannot be kept in the same tank. Here is a comprehensive guide to finding other fish that can live with bettas.
You should never keep a single fish in the same tank as a siamese fighting fish as they will constantly bully the same individual. That being said there are very small heaters available at most local fish stores. Make sure that the water in the tank is slow flowing.
Yes the only fish you can t put in the same tank is a male beta with another male bata. Some small catfish sold for aquariums get really large as they grow. Here are some of the main points to remember when introducing corydoras to bettas.
I have a male betta and i didn t know if i could put him in the same tank as the betta also i am unsure of the breed of catfish he is tan with brownish red spots but they are kind of hard to see. The water in a betta fish s tank should be kept between 75 to 86 fahrenheit. Betta fish are reputed to be feisty aggressive and territorial and are often quoted as bad aquarium mates.
However remember that you don t want the water current to be too strong otherwise your betta will have a hard time swimming. This feature is seen more in male betta fish who are very territorial with other males of the same species. While bettas will stay at the top of your tank for the most part corydoras will stick to the bottom.
My personal opinion which is based on decades of personal experience and also on as much research as i ve been abl.
