Good morning all
Being in the same situation as Crusty, a new owner to be, I keep hearing people say that I/we could possibly get 2 Cresties to go in the size tank - the 45 x 45 x 60, which is what I have. What happens when they get older though if they either turn out to be 2 males who may be aggressive towards each other, or a male & a female who gets harassed around breading time?? Do I have to get another set up to house 1 of the Cresties?? Would I be best just getting the 1??

Definately better off just getting one to begin with. You would have to seperate if they both turned out to be males as pretty much, without doubt they would start fighting. Some people or shops might tell you that a pair of males they have get on ok but they will always start fighting at some point.
If you had a male and female pair, it is advisable to seperate the male in breeding season as he will constantly pester the female and this can be very stressful for her.
So basically if you want two then you would need to seperate them at some point unless you had two females but then they don't always get on with each other.
