It means the lid on your container needs taking to the doctor.
Well, :roll:
That's how it is pronounced anyway.
It's just a designated name for a classification of a family of fish.
Some C are suitable as community fish, but choose their tank mates carefully.
Research the ones you see in the LFS, and would like; on the puta.
Lots of these grow to a ridiculously huge fish, and also viscious-as, so buyer beware, otherwise you'll be needing new tanks quickly.
What is the special thing?
MMMMMMMM
I think it is the shapes, colouration, behaviour, and probablyy most of all, their various breeding behaviours, and different techniques.
The main one I think is the mouth-brooders, absolutely amazing. Especially for first-timers.
Are there special "things" required.
Well yes, pH in my mind, a lot come under the acid side of it, but there are also a lot on the alkaline side, with these in mind of course comes the softness or hardness of the water.
Once again, do your research before you buy.
Your final part about a "silly question".
The only silly question is your question that you don't ask! ! :roll:
Are you in an area where there is a fish-club.
If so, join it, they, I'm sure will be able to keep an eye on what you are doing and help you thru various problems that arise in lots of cases.
