I've had my 4 cichlid's for about 6 or 7 months now and for some reason they just all of a sudden started fighting and acting weird. I have 3 electric yellows and one gray cichlid. Not sure what they are called. They live in a 55 gallon.
I was watching them after I did a water change today and I noticed that the gray cichlid and the bigger yellow cichlid (the two fish to the far right in picture 3) were constantly fighting. I also noticed that the bigger yellow cichlid was hiding under a plant leaf in a corner which wasn't where she usually hides. She's been doing that for a week or so now.
I added in that ship that's in the front thinking that I didn't have enough hiding spots for them. The bigger yellow cichlid gets inside that ship now but they are still fighting. They chase each other in small circles and open their mouths really big and sort of pinch the other one on their bodies. Looks very mean.
Do I not have enough hiding spots? Should I add more cichlids? (That should be my last resort because I don't want to add more fish and then they get picked on too.) Do I not have a big enough tank?
I checked the ammonia and it was 0. I didn't feel the need to test everything else but if suggested, then I will. (I'm kinda getting low on my ammonia and nitrate liquids in my API testing kit.)
I started out with just the fish in picture 2 and the big yellow fish to the far right in picture 3 in a 29 gallon tank because a LFS
said that they would do good in it. Well, they picked on each other constantly so I went back to the LFS
and asked what was wrong. They said I needed a bigger tank with more hiding spots and that I needed a male in the tank. So I got a 48 gallon tank and added another electric yellow (male-i hope in picture 4/the LFS
said it was a male) and that gray cichlid. They lived peacefully. Then I upgraded to the 55 gallon they are in now. They have been inside that tank for about a month now. And today is when I noticed them fighting.
Also, if anyone knows the type of cichlid the gray one is or the gender of each of them, I would be really grateful. I have tried researching the gender of the Labs and I still can't tell any difference.
