HI all! I have had my Oscar Delta for almost a year now, and I have a story to tell. Right now Delta is in a 130 gallon aquarium with a few catfish, A blood parrot cichlid, and a kissing goramie. However some of you may remember clyde, my big boy oscar. Delta is around 7 inches long right now and captain is around 8 inches long. However clyde was 10 inches long. I got clyde at 10 inches long (he came with my 55 gallon tank that I got), and ever since delta was with clyde, delta relied on clyde. Delta is a wimpy oscar, he doesn't like to start fights and he doesn't defend himself much when he gets in fights (its not like there is a crazy amount of fights going on but general fights just to establish territory). Captain (my blood parrot cichlid) is the boss of my 130 and he likes to let the other fish know. He isn't a bully by any means, I mean he is 24/7 harassing my oscar but he just likes to let the other fish know where his territory is. Anyway delta would always got to clyde anytime he got in trouble and clyde would always protect him. Clyde and Delta even started to nest and I think they would have laid eggs, however about 2-3 days before christmas clyde jumped out of the tank (despite hiving a lid, he knocked it off) and passed away. Clyde was the fish to keep the other fish in check and at the time of his passing I had a flowerhorn in the tank and clyde was the only one keeping him in line. Non the less I had to get a 40 breeder for the flowerhorn because he started to bully the other fish. Ever since clyde has passed I have noticed that delta isn't quite the same. I have heard about fish that get depressed (specifically cichlids) after there partner died but I never really believed it. However ever since clyde has passed Delta tends to hide more and isn't as enthusiastic about eating. He still eats and still swims around he just doesn't have the same spring in his step as before. I decided that I wanted to get him another oscar friend so right now I am growing out a albino oscar to go in the tank and (Hopefully) cheer up delta. I feel bad for him but hopefully he cheers up when I get that new oscar in the tank. Let me know what you think about this and let me know if something similar has happened to you. IDK why I made this thread about this but I guess I just wanted to put down some more evidence that fish have emotion (as I know people who still don't believe that).
