Muriatic acid is known, I thought it is used to cure concrete ponds
and is harmful to fish. If I am not mistaken it is HCl, so one of
compounds is very toxic to fish. What if Cl in certain conditions is
released to water?
It is a chemical reaction of any acid with a base or organic.
You get bubbles.

Well, not really. There may be some situations where that's true, but in
the typical case: HCl + (x)OH = HOH + (x)Cl
IE, water + a salt. Where your most likely bases are Ca(OH)2 or Mg(OH)2
there's no problem. I failed organic Chem, so I can't say what happens
with organics :-) I guess there's a possibility of producing
organochlorides - bad for us in the drinking water, but I don't know how
bad they'd be for fish.
