Hi there,

Could anyone tell me if there is a diffrence in colour between the white/black Calvus when they are Juvi's ???

I have both colours of Calvus but i am a bit confused about one of the "white" ones. He has more white on him than any of my Black Calvus but his barring seems darker than the other White ones i have he also has darker fins than the other white Calvus i have.

He came from a breeder who has the white and black Calvus in seperate tanks so he said all of the ones that were meant to be white will be white but i am unsure about this little guy.

Do white Calvus change from a darker colour similiar to the black calvus as Juvi's then change to more white/brown as they mature?? I hope so as he doesn't seem to look like my other Whites but also looks to have a lot more brighter white on him than my blacks so i am just confused lol. Please Help !!!

Ashley.

All the Altolamps can change colour at will. A darker colour usually denotes dominance. Is this fish the most dominant in the aquarium?

Thanks for the reply.

No i don't think this guy is the most dominant in the tank. It is defiantly the larger white Calvus who is the boss.

Could someone tell me if White Calvus are a darker colour when they are Juvi's or if they are just the same white colour when they are born??

Fish, even little fish, change color at will. There is no way to tell the difference between white and black calvus juveniles. It's difficult enough with the adults!

i have a black calvus and infins and you couldnt tell the difference only on the specs on the fins as for color as juvies they look the same there about an inch in size. one of my blacks has a black tail fin and thats the only difference and they do change colors thats for sure i was the same way when i got my fish. :fish:

I was asking this same question a while back!

As best as I can tell, white calvus and black calvus start out looking almost identical, and then they gradually differ in color as they get older. I have a black calvus about 1 1/2 or 2 in. in length, and it went from looking kinda bland and dull, to now looking pretty cool. It's getting darker and the sports are really starting to emerge.

But, as other posters mention, these guys drastically change color at will!! It's kinda neat.
