FIRST- dont feed live feeders. try and get them one pellets or nothing live. due to diseses and other stuff that can harm the bass.
SECOND- I started with a mono, it doesnt rfeally matter what breed, but me if ur unexperianced with cichla then dont get a high $ one.
THIRD- Its FUN, if you decide to do the cichla, make sure your tank will be big enough. 210 gallons +is my opinion. I have a 300 gallon with 3 cichla in it and they seen to love it.
But just do a little researh and the rest is happiness
