Got a video and some pics of my black pearl calvus. I got 4 from one shop not too long ago (a week or 2 back) and then bought 1 more 3 days ago. One of the calvus has gone white, while the other 4 are nice and dark black coloured. Is there a reason for this? I was thinking maybe a dominance thing? The calvus that has gone a pale white colour. It looks happy enough. Eats well and cruises around the tank.

Hi mate how are ya. I personally wouldn't be to worried calvus can change depending on there mood I have found but I'm sure more experienced people have a more detailed reason.
Nice fish good luck with them. Cheers

I have 2, pretty sure we got them from the same shop. 1 is definitely darker then the other which looks a similar colour to yours so I'm guess it's a dominance thing. I'll try post some pics tomorrow.

I'm good thanks bro. Yeah not too worried, just wanted to show off my sexy fish!

That would be sweet man! I'm really looking forward to seeing them grow up, as calvus look sweet when they're bigger.

I don't know jack about tangs, and was just concerned he might be unwell. I just dont want to lose any fish, as they take ages to grow, and I can't ever find any nice big tangs for sale.

Yea could be a dominance issue, could also be a locational variance. I actually prefer this type of colouring in the calvus, so if you don't want him i'll take him . Calvus vary in colouration from completly black to stripped ( my preference) through to the whitish . As with all fish, different collection points can have slightly different colouring. My original breeding calvus were black but i've now changed over to the stripped. cheers Steve.

Here's some dodgy photos but you get the idea.




They are going to be moved into a new tank soon.

ok thanks for that. i'm guessing that the one that has gone pale white is the last one i bought. i picked it up from a different sponsor to the first 4 that i bought from another sponsor store. when i put it in though, it looked exactly the same as the other 4. Who knows? Cheers guys

Some times they take a while to settle in and work up the confidence so to speak. I had gold comps that go real dark just after the lights go on. Young fish also dont display full color until they find their place. Just some of my experience

Yep it must have been a settling down thing. All 5 calvus are a nice black colour now. YAY!
