A quick and easy city cache (a short multi)...
There's no need to solve any difficult ciphers or read long listings or walk long distancences. You only need to check the aquarium carefuly.
Don't come too close to the riverside (it's not necessary) and don't feed the fish!
Nepriblizujte se moc k rece a nekrmte ryby!
At the starting coordinates you need to find out / Na uvodnich souradnicich musite zjistit nasledujici udaje:
The number of small fish on the left side / pocet rybek na leve strane = A
The number of small fish on the right side / pocet rybek na prave strane = B
The number of small yellow fish / pocet zlutych rybek = C
The number of large fish / pocet velkych ryb (savce pocitejte jako rybu ;-) = D
F = C
I = A - B
S = A
H = A + B - D
If you see an octopus, you've got a twenty-twenty vision, congratulations / Pokud vidite chobotnici, mate vyborny zrak, gratuluji!
Is there a shark in the aquarium / Je v akvariu zralok?
Yes / Ano: X = - , Y = +
No / Ne: X = + , Y = -
The final coordinates / finalni souradnice:
N 50° 33.993' X (FI)' E 015° 54.318' Y (SH)'
Happy fishing 
Don't forget to bring your own pen (There should be one, but you know the cachers...) / Nezapomente si radeji prinest tuzku
