yes, my turtles lived with crabs but ate them, but I also had crabs in with my minnows and they did fine. There is always the chance the crabs will eat them, but it also depends on the crab. with hermit crabs, it would be fine, but some are carnivorous and do eat fish, so it depends, but most alot of people keep fish with crabs.
i dont know try to put it in its food a see what it does they are omivore so they will most likely eat it.
no
No they can not as crabs will use claws to catch and harm them.
they can live in goldfish bowls i have always kept my beta in a goldfish bowl and my last beta lived between 4-5 years in a goldfish bowl.
Small or Big it should be kept in a huge tank with Filter and Oxygen 10 gallons per Goldfish At least
NO U WILL KILL IT!!!
depends, can a ten gallon tank live in a goldfish
Yes
You need a lot of things, unless you are raising goldfish in a bowl. You need: (for a tank) A filter A tank (not recommended under 5 gal.) Goldfish food Gravel Live or fake plants (underwater plants) Air pump (not required) Choice of decorations These can be very expensive sometimes, but it will keep your goldfish living longer and happier than in a bowl
Yes, like all pet fish, goldfish need more oxygen than can be provided by just a bowl of water.
Goldfish just need a plain bowl and some plants
No you schould not have that many fish in a one gallon tank. Thats the size of a big betta bowl. And because they are goldfish it is worse their poops are toxins
Goldfish cannot live in bowls. Fancy goldfish need at least 20 gallons for the first fish, and 10 gallons minimum for any additional goldfish. This means that for two goldfish, the smallest tank you should have is 30 gallons.
Three in a bowl? To live its full lifespan a goldfish needs ten gallons, so if you want three, you need to have a 30 gallon tank. Or 3 individual 10 gallon tanks. Otherwise they will live a month, maybe.
