Stocking Qty For 200Litre Tank

[jkilby]

I have just got a 200 litre tank (100x40x50) and am just getting it set up it is now chuging away getting ready for the fish in a few weeks, I was just wondering on a few questions regarding stocking

1. Rule of thumb, how many fish should I put in a tank of this size?.

2. I like the Satanoperca Jurupari that i saw in my local supplier, but it says (like the silver dollar fish) that it shouldn't share a tank with small fish. What is classed as small?, would they attack cardinal tetras or lampeyes, as I like these as well, or do they mean fry?

3. Are Knifefish worth getting, I like the look of them, but are they a fish for a beginner?.

4. Invertibrates, are there any shrimp or crabs that will live side by side with fish, or will they just become a midnight snack!!!.

I would appreciate any advice that could be given.

sorry to tell you that the knife fish are not the fish for a begginner as there isnt many suitable tankmates as they will maybe eat your cardinals and the lampeyes

ask someoneelse on everything else but im pretty sure that knife fish arent beginner fish
