Sorry for replying to myself, but I found some further information on this that might be quite interesting (and sad). WDC released a press briefing based on the files they received from the Nuremberg zoo in 2016 [0], couldn't find an English version and the full report was supposed to be released in summer of 2016, I also couldn't find that. But what's described in the press briefing is already bad enough. On page 4 and 5 they list examples where dolphins got treated with Diazepam and even males with synthetic progestogen (female hormones) to influence their anti-social behavior resulting from the poor living conditions They even administered Diazepam to pregnant dolphins, the calf needed to be treated with antibiotics regularly because the mother would keep hurting it and in turn, the mother would get Diazepam in an attempt to tone her behavior down. Because the anti-social behavior is so common dolphins regularly have to be isolated, furthering their mental issues. Tbh none of this is surprising to me, in nature these animals are known to make 4.000 km journeys, 90 km a day, diving down to 500 meters. In Nuremberg 9 of them are stuck in shallow concrete pools with the total area of 1/4th of a soccer field. No room to evade social conflicts, nothing exciting to discover so, of course, these very intelligent animals are going crazy in such an environment, I know I would.
