Had my 55g set up and running for two days so today I went to the local fish shop and asked a couple questions to confirm some things I had read up on to see what there opinion was. I went with central and south american cichlids for my tank and have a video of what they look like so far. I know I have two jack dempseys that are about an inch and a half the other two my girlfriend picked from a tank that the owner said would go with the jack dempseys but when he said the name I didn't see it on the tank lable so maybe someone could help me out. The orange ones in the video I thought he said were parrot something but I might of misunderstood. Only questions I still have is how long should I leave the aquarium lights on for them? He told me to feed them twice a day and each feeding put small amounts until they look like there eating slower and slower is this right? I'm feeding flakes and they seem to like them but also bought frozen blood worm cubes. Will dropping one or two cubes a week for them harm them any? All the fish seem to be getting along fine the only thing I've noticed is when the jack dempseys swim near each other one chases the other around the tank for a while. Is this because they are the same sex or maybe different sex? The owner of the shop said they were two small to tell the only difference in them is the one that chases the other seems to have darker colors on it. Apperciate all the answers and any help I can get!!
