Glad to see that you are happy that you got fish, however, you are going to be busy for awhile!
Also, what type of Cichlids did you get?
As Cichlids really only occupy the water column from the substrate up to a foot of water, so they are pretty much bottom dwellers for the most part.
Cichlids NEED a lot of surface area of substrate,
not water height like in your case.
Also, Cichlids NEED a lot of hiding places!
Also, Cichlids should be in groups of at least 5-6, and that is just not possible in your tank.
They also grow to 6+ inches, so two of them full grown would stretch the entire length of your tank.
It is too late now, since you already got the Cichlids, I just thought I would let you know for next time, that your tank is not suitable for Cichlids. Sorry.
Here is a pic of my 29 gallon tank with Cichlids in, and this tank is too small for Cichlids, fortunately I have a 55 gallon tank that I ma currently setting up.
Once again, I hope you do not take this the wrong way, it is more or less and informative write-up to why Cichlids are not suitable in your tank.
Now that you know for next time, I would focus/discus on this forum suitable fish for your tank in the future.
