Fish Suggestions For My Tank?

[didz04]

Hi I have cichlids at the moment in a 4ft 40g.
The fish that I have in there are:
1 African Congo cichlid
1 Yellow lab (will it be important for me to get more?)
Johanni cichlid
2 malawi cichlids
2 socolifi (blue) cichlids
2 Jewel cichlids (not sure what type though)
1 Dora catfish
1 Sucking loach

I was hoping for another type of cichlid that is very nice looking and would be fine with my setup. Would any of the Julidochromis be fine with them? Also are there any other types of fish except cichlids that would be fine with mine, maybe a 2 pictus catfish.
I have just made changed my tank setup full of rocks, I wanted to also check if these are Ocean rocks, if not then what type of rock isit and would it affect my fish in anyway (water quality)?

Setting them up.

All setup without fish in yet

Its my best setup so far and also first real cichlid setup
Still haven't got any more pictures of the tank with fish in except videos, but will do soon.
Anyhelp and suggestions please and thanks in Advance.

The rock looks great I think the main concern with rocks is that they contain carbonates which you can check for by dropping vinegar on them-carbonate rock will fizz.
But, from what I understand of cichlids (not that much!) they like high pH and high hardness? So I would think most rocks would be OK with them. Those rocks do look very chalky. Maybe try posting this in the cichlid section, esp. with regards to other suitable fish?

Yes, that is ocean rock, which will raise the pH and hardness, however this is a good thing for definite with African lake Cichlids. I don't really know how pictus cats would do in there, sorry.

Thanks for the replies. I thought it looked like Ocean rock but since there could be hundreds of different rock people put in their tanks I thought just to double check. Soon I am going to check the ph and might do another 20% water change as it still looks slightly misty I can tell as i cant see the black background clearly. I have posted this in the African cichlid section but no replies, I guess will have to just wait for a reply. I know that pictus are fine with these as I kept them with these cichlids before but not to sure about the hardness and high ph, going to do some research. Also what type of plants would be best in this type of setup, mainly for looks, I was thinking since the tank is quite tall I wanted to put in some fin tall plants. Maybe one big bushy plant for more cover for the fish.

I have a alot of rock in there filling in almost the whole back, will that affect how quickly it will make my water harder and will more rock affect how hard the water is (dh)?
What fish would be suitable for hard water? I mean if I started again in fish plan but with the same setup with the way it is now.
