How much experience does everyone have with the different species of calvus? I'm doing the mbuna tank first. But I'm planning on getting another big tank when we build our house this summer. Something about the Calvus really intrigues me.

I have bred Alto Calvus and Compressicceps. What would you like to know?
FYI, not a good chose for a mbuna tank.

I'm not going to put them in the mbuna tank. I just want to learn a little about them for a future project. Are they fairly easy to take care of? I've read somewhere on the net that they were a little difficult.

They need good clean water that doesn't fluctuate. They like PH and hardness high, and like a meaty diet, anything with a shrimp/spin. mix would be fine. Joe can give more info.

On a scale of 1 through 5, 1 being easy and 5 being hard, I would rate them as a 2.
Tank size, I would go with a 20L or a 29 for a pair or a trio.
Water is one of the most important factors. I like a PH of at least 8.6 to 9.0, Hard water around 200 to 220 ppm, temp around 77 to 79 degrees and Very clean.
I do 25% water changes weekly and on fry 25% twice a week.
As far as food Brine shrimp, some flakes and blood worms is what I feed.
Don't forget some rock work and shells they like to breed in shells.
They are slow growers so if you get small fish they will take sometime to mature.
Don't mix them they will cross breed including calves and comps.
Lastly they will eat other fish fry including their own. When their babies are free swimming I take them out and raise them in their own tank. I can easily do this because the fry will normally hide in the shell they are born in for at least a couple of days after they are free swimming.
hope this helps.
Joe

It helps alot. How big do they get when they mature and how many should you keep in a 125-150 gal tank?

You can keep alot in there if it is a species tank- I would say 40 or more. Most people wouldn't have a species tank that large, but with Comps or Calvus I think it would be awesome. I would do a Tang tank with a tank that large. If you want a species tank you could do a 40L-90gal.

Problem is most people don't think of what is going to happen when the fish mature and start spawning. In a 125 - 3 or 4 pairs or trios in my opinion would be tops. If I were setting up a 125, I would get around 6 medium all of the same type grow them and let them mature and I would get a few other types of tangs that have the same diet requirements. Keep in mind in a multi species tank spawning will happen, but with the other fish in the tank, you will most likely not get any fry from them because the other fish will eat them. However after they are sexable you can put them in smaller breeding tanks, let them spawn and get fry.
Calvus and comps get to be around 4 to 6 inches and can start spawning at around 31/2 to 4".

I didn't know they only got to 6" max. Thought they were big fish. Cool!

Joe, if you went all male, without trying to breed, and or male female and not worrying about the fry, How many could you comfortably pack into a 125g, I've kinda just wondered this for myself- Also could you start a thread about raising their fry, because I haven't done it yet but I hear it's a little difficult.

Thanks alot guys. I really want to try a calvus tank in the future. They seem to be really interesting fish.

I would take Joe's advice on this and get 6 small ones.
