Okay, so my girlfriends brother has a tank in his room filled with Cichlids. I think its a 30g bowfront but it might be a little less. Apparently, without telling anyone, he stopped taking care of the tank a few weeks ago. He just went away to college and I guess he just stopped taking care of it. His mother asked if I could get the tank back in working order and teach her how to take care of it because she wants to keep the tank going.
Anyway, they went down to take him to school yesterday so while the where gone I went over to their house to check on the tank. The water was a cloudy yellow color, many of the fish had red ammonia burns on their gills, and the tank seemed pretty dirty.
I didn't have a lot of time so the first thing I did was a 50% water change. I just knew that the tank needed fresh water. I tested the following parameters and these were the results:
Ammonia - 8 PPM, test tube was dark green
Nitrite - 0 PPM
Nitrate- 5 PPM, maybe a little higher
Granted this was after the water change, so this could have been much worse. That was all I could do while I was there. I picked up Prime later that day and am going back over in a few hours to do another water change and clean the gravel. I had to get a new siphon because his didn't reach the bottom of the tank.
Now, here is where my problem lies. I know how to get the Ammonia down, but I know nothing about these Cichlids. I don't know what type they are. I don't know what they need. I don't know if more should be added when I stabilize the water parameters to prevent aggression, or maybe some other type of fish. I'll be posting this both in the Cichlids forum as well as the Beginning forum just so it gets the most views. Any help would be most appreciated.
I'm attaching some pictures of the fish so I can have some help with identification. They aren't the best but hopefully it's enough.
