cheers barbie, thats great. im actually located in the uk, so both are a very long way away, but thanks alot, and if you know anywhere over here any good itd be much appreciated! thanks again. ben
just one final thing, how many males and females of each? sorry im fussy i know, next thing ill be asking you to come and set the tank up as well! cheers
Young calvus are impossible to sex, and older calvus can be quite expensive, and are usually only available as wilds. They grow very very slowly. If you're going to buy adults, I'd recommend 2 males and 4 females personally, with two separate rock piles for them to claim and defend.
I used to do commercial tank maintenance, but I think the plane ticket to get me there just to set up a freshwater tank would be a bit cost prohibitive
