I would strongly advise you NOT to do a planted tank with Cichlids, they eat most plants and will constantly uproot them.
You need to decide for the 55g tank which fish you would want to keep, Cichlids should be kept in a species only tank with ONLY synodontis Catfish or BN plecos, no other smaller fish, the cichlids are too aggressive for most and will more than likely eat them.
A 10g tank is way too small for a cichlid, they need at least a 30g+ tank as they are extremely active fish.
Cichlids are also classed as aggressive fish, which is why I would recommend not keeping them with anything other than what I have mentioned.
Have you cycled the tank?
If not have a look at this
for how to cycle the tank.
If you need help with stocking suggestions then please do not hesitate to ask.
