First: a "janitor fish" is what Americans call a pleco.
Second: yes, you can keep a Betta (fighting fish) and a pleco (janitor fish) in the same aquarium. Plecos are only aggressive to other plecos, so your pleco won't eat the betta. The two fish live in different parts of the aquarium--plecos at the bottom like most catfishes, bettas at the top because they're airbreathers. A betta has the common sense not to mess with a fish as big as a pleco--and it wouldn't matter anyway because plecos are armored fishes. Plus, bettas love to eat snails so they are a good addition to your tank maintenance team.
Now! This is the problem: Plecostomus catfishes get huge--if your fish isn't a foot long two years after you get it, you're not feeding it enough. (Plecos eat things like zucchini pieces that you weight down so they sink.) It is a fish that needs AT LEAST a 55-gallon tank to live and be happy. If you've got a small tank like a 10 or a 20 gallon (40 or 80 litres) I would get either Ancistrus catfish (like plecos but much smaller), Corydoras catfish or upside-down catfish.
The Jewel Vision 260 Aquarium is suitable for keeping one Siamese Fighting Fish. One can also keep other tropical, marine and coldwater fish in this aquarium.
yes, goldfish and betta fish fight.One time I had 2 goldfish and one bit the other one and it killed it.Never have 2 betta fish in the same aquarium or bowl because they will fight right when they get in the aquarium/bowl!
If you think you're Siamese Fighting Fish is getting overweight, you can just cut down on feeding them. I have one ten gallon aquarium and one sixteen gallon aquarium, and I feed the fish in them once a day, and they are very active and healthy.
You can put one maybe 2 one-inch fishes in your one gallon aquarium
NO!
it is warmer water in the corner
nothing the fish will be fine (they can live in just water u know)
the rule of thumb is usually one inch of fish per gallon
If you have two crowdstar fish one male and one female and they mate by chance there baby will be a green crowdstar fish.
A fish bowl. Or even a bathtub... any thing that holds water. But it's est to have a aquarium with a filter and one of those heaters. Otherwise, your fish might die pretty quickly.
