Just got these guys home Sunday. They seem to be setteling in to the new tank well even with the lack of structure. Hoping to get some more rocks and shells soon. I have 2 shells 1 on each end of the tank and a rock structure in the middle. Their tankmates are 8 Tri colored cyps.

Very nice! Congrats!!

How big are they?

I do have a suggestion, I would turn your shells on end like the picture below. You calvus will like that much better.



Please keep the pics coming.

nice! although the ones with yellow could be yellow calvus.
One of the females does have some yellow on her snout between her eyes but thats the only yellow on her. The lights in the tank are kind of crappy and have a yellow tint right now also. I have had yellow Calvus and they look nothing like these guys.

The yellow on the head is normal for some calvus. My 'white' calvus have it occasionally, comes and goes. Look at Razzo's pic, same thing.

Nice fish, btw.

Thanks. The one female has a lot right now, the Male has a slight yellow tint and the other female doesnt have much yellow at all. It will be interesting to see how they change. I believe the one with the yellow on her head right now was the one that just produced the fry a week or so for the previous owner.

If yours stay white, count yourself fortunate. My 'white' calvus turned much darker when they reached maturity. Occasionally, I see them showing as expected, but not often.

No, there are alternatives such as rock structures, caves etc. Shells are cheap and what my fish were already used to.

As mentioned, rock structures will do nicely. Shells are perfect for breeders - if your not worried about breeding, I would have fun making rock structures.

Yeah those are definitely whites. The white hues in the dorsal are a dead giveaway.

The "true" White, I think comes from a very many variables. For example:

The big one is my WC male, he looks more like a black most of the time. If I move his excess females out and leave him in a single pair he glows white like a light bulb (I can elaborate, a great deal :lol: , on coloration of Calvus, in a pm or something :roll:)

The female in the above pic (The White one) is available for spawning and carries that coloring regularly when she is in condition. The grayish female below the male is guarding a hatch having recently spawning. The low dominant female is up to the right and also in condition.

IMO, it is true they all darken with age but the females, in my setups, still seem to pursue "modes of coloring" during certain states of being etc. whereas breeding males stay pretty dark almost all of the time after about 4-5 years of age

BioG,

I know you went through all this is in a pm to me before, but if a male was left alone, would he lose the dark coloration and take on the white color? Or is the best way to get white calvus that show as white to just go with a female(s)? And those pics we see out on the Internet or in books of the white calvus that look like your female, are they probably always females?

The best answer here Is, I don't know :oops: I believe I have kept a single male before who, in his isolation, did go white but there were a few variables in that he was under 5 years and was isolated for treatment (Can't remember what for). I can only speculate what females would do if isolated as one sex.

I assume they would go white for the most part. The only variable I can see in that situation is that Dominant females can be quite aggressive, especially when ungoverned by the presence of a larger male (The male's I've noticed seem annoyed by prolonged female squabbling and tend to step in effectively ending the dispute, although he'll almost always rule in favor of the dominant female :) ). During such aggression, harassed females will, in a sense fall out f conditioning and revert to a more defensive and/or submissive coloring depending on the extent of the harassment.

I would say that the best situation for the most "white" to gray or black ratio in your white calvus setup is a Dominant under the age of 5 and as many females as he'll tolerate. This way you'll have, hopefully, a few white colored females swimming around with basically only the dominant pair displaying variations.

Although I will add that I think of Calvus as more of a family fish than a "harem" fish (Until they get old and grumpy :lol: ) mainly because all these pleasing colorations seem contingent upon the relative comfort and happiness, for lack of a better word. I hope that helps but to reiterate I have never kept sex exclusive groups or singles, outside of quarantine for whatever reason, so I can't say for certain :thumb:

Thanks for the compliment, although I'm no Razzo with a camera :p . Now that I look at the pic (I took it only to document the "modes" of coloring I was observing simultaneously and consistently) I'm embarrassed as to how random the shells are and how junkyardy the rock pile was :lol: :oops:

I'll have to take some new ones... Or maybe I'll just let Razzo deal with the pics! :D (If I was a millionare I'd fly Razz to my house to shoot my tanks!)
