The only catfish I would try to keep with large cichlids is something that grows large and can defend itself like a Plecostomus. Don't expect any catfish to eat rubbish or poo. They won't.
I have an Oscar Cichlid in the same tank as mine and I also used to have it with guppy's.
Yes they can... but I was with the most Mbuna, they cannot be kept in pairs.
They are egg layers and will lay their eggs on a smooth surface surface inside the tank.
No, it currently doesn't have water in it.
I would advise you to get rid of the Jaguar cichlid (Parachromis managuensis). These fish grow too big for a 10gal tank.
There are many. Far too many to list here.
It is possible if the tank is sufficient in size and provides enough territories and enclosures.
Sometimes Cichlids change color when the temperature of the tank drops or rises suddenly. From my experience. -Alan Armour
No, a firemouth cichlid (Meek's cichlid) cannot thrive in a saltwater tank. They are freshwater fish that require specific water conditions, including low salinity. Placing them in a saltwater environment can lead to stress, health issues, and ultimately death. It's best to keep them in a properly maintained freshwater aquarium.
Yes.

When choosing tank mates for cichlids, it's important to consider fish that can handle their aggressive behavior. Some compatible tank mates for cichlids include certain species of catfish (such as plecos), some species of barbs and tetras, and certain types of bottom-dwelling fish like loaches. It's crucial to research each potential tank mate's compatibility and care requirements before adding them to a cichlid tank.
