No,,not all cichlid's are bad.We can read and hear it all over, in books, on the internet and from lots of people. Cichlids are territorial, they dig, they kill each other and all those stories. But is it true or does it just make a good story?
How about a small case study that indicates not all cichlids are the same.
Can we call it "Grandfather visits" ?
A 75 gallon tank with lots of wood and rocks for cover where 6 rainbow cichlids live and breed. A young pair have laid eggs and now have wigglers when the largest male approachs.
Does he dash in, beat up the small fish and eat the fry?
Or does he approach them slowly and let them know he means no harm?
Maybe he even greets them and checks on the grandkids?
After he leaves the small female still guards the little black pile of wigglers down in the corner.
But that can't happen. All the books say cichlids are killers!
NO! Not all cichlids do that! Some are just plain sweet but you are not likely to see that written in most books.
So just don't believe all you read. I find some of the "experts" who write books may not be that good on the subject. Some of the information you read is correct. Some is totally wrong.
Pick your information carefully and you may find cichlids are not all the same.
Have kept and bred the herotilapia multispinosa pictured,and these along with Keyhole cichlid's are quite mild compared to some other's.
Sometimes however thing's change as the fish become older, or when protecting fry.
I found the rainbow's to be excellent cleaner's of algae from wood,rock's, But they mowed down my hair grass like duck's on a june bug, and dug spawning pit's all over the tank preventing some stem plant's from ever getting root's down.
Larger leafed plant's did well.
