Yes. Neither fish have any special needs that would interfere with the other. They both need 1 gallon of water per 1 inch of body length, they both need a cycled filter running 24/7, they both need to have 50% of their water changed weekly and they both need a water temperature of around 75F.
As long as the tank water is clean, and the fish are being fed properly, the catfish may just be entertaining itself by swimming that way.
Cory Catfish tank mates include most community tank fish as long as they are non-aggressive and friendly in nature. Otocinclus Catfish, Tetras, Swordtails and of course other Corys can be a good fit.
I have an Oscar Cichlid in the same tank as mine and I also used to have it with guppy's.
Adding a Cory catfish to a red-eared slider's tank is generally not advisable. Red-eared sliders are omnivorous and may see smaller fish, including Cory catfish, as potential food. Additionally, the water conditions and habitat needs of these species differ significantly, which could lead to stress or health issues for the catfish. It's best to keep them in separate environments that cater to their specific needs.
Technically, a 2 gallon tank for one Cory cat, 4 gallon tank for two Cory cats, and so on. The rule is one gallon per one inch of fish and Cory cats can grow to two inches, although the bigger tank the better. I would DEFINITELY not recommend a 2 gallon tank with one Cory cat. They like to be in groups and will be happier and healthier.
I once saw a catfish in my fish tank swim up and take food away from the pyranha I had in there with him. That pyranah absolutely would not mess with that catfish amd they were about the same length.
Cherry Barbs, Cory Catfish, Zebra Danios, Platies, and some Mollies, but Mollies tend to bite the bettas tail. You have to have a bigger tank if you want to have a community tank. The general rule is 1 inch of fish per 1 gallon. I've also had some luck with the small Tetras.
Provided the tank is large enough and the catfish is a tropical species there should be no problems.
No catfish is an aquarium cleaner. There is no such thing as a fish that will clean a tank.
i have 1 female betta 1 platy 4 neon tetras and 2 catfish in my tank and they all get along fine
Some types of fish that can safely coexist with betta fish in the same tank are peaceful community fish such as neon tetras, corydoras catfish, and ghost shrimp. It is important to research and choose fish that are compatible with bettas in terms of water parameters and temperament.
Bettas go great in a community tank. Tetras, Loaches, and Cory Catfish all go well with Betta fish. Anything that doesn't have large, flowing fins and isn't a fin-nipping fish will do well. Just be sure to add the Betta last or he might be territorial and vicioius toward the other fish.
