Рыба ok, but sounds little bit like "риба", "Р" should be strong and solid

Театр - 1. can`t really hear first "T", make it stronger 2. It is not театор. Should be (Т`эатр), with no spaces between "тр".
"Р" is ok.


Рядом "Р" is alright, but should be soft (unlike рыба). Otherwise, you get РАДОМ (Like in "Верховная Рада Украины" - Ukr. Parliament)

Словарь - good, but "р" here should be softer. Instead of your "словар" it should be "словарь".

Нравится - no matter if it is "Нравится" (me \ he) or "Нравиться" (infinitive) - always pronounce "ЦА" ending. With no separation он "тса"... And in any same word (делаться, слушаться, говорится, видеться etc )
