Stocking 100l

The 'inch per gallon' guideline refers only to fish that reach an adult size of three inches or less.

It's not just about whether fish will 'fit' in your tank, stocking wise, it's also about making sure they have enough space to swim about. Technically, you could keep a single clown loach in a 100l tank (if you did enough water changes to stop it becoming stunted), but it would barely be able to turn around; no life for an active fish. They are also very, very social fish and it's really not fair to keep one on its one. The stress of being alone will cause it to be more prone to diseases, like whitespot.

I would also say that you're massively underestimating the size of your fish. When doing calculations like this, you must use the eventual, adult size of the fish, not the size they are now. So your four cardinals would be eight inches, not two, the embers five, not three and the panda cories six rather than four.

If your plec is a clown plec, he can stay though.
 
i agree with flutter mouth the inch per gallon rule is way of, it's like saying you could keep a 2ft long wolf cichlid in 30 gallon and thinking you have 6 inches worth of fish to spare,i'd up the shoals but if you like the clown because its the most interesting large fish you have you could look for another center piece that would fit nicly perhaps some rams or a few khuli loaches but i'd defintly get rid of the clown loach the pleco can stay though hope it all goes well

2 inches adult size for cardinal tetra? Adult size they're like 3cm which is about 1.25 inches? Also I thought when considering fish size you only count their actual body size not fins/tails etc.

Oh and yes according to LFS it is a clown plec
 
Adult cardinals are about 5cms I believe. I think as long as you get your clown loach out it should be fine but I wouldnt really add more fish unless its 2-3 more cories.
