Yes, the fish you have are,, as you have noted,messy eaters. Removing more water during water changes ,and vaccuming one half the gravel and a different one half each week will help.
I would aim for 50 percent water changes once each week.
Gravel will need to be vaccumed each week for the fish you have and adding a second filter may be needed as well depending on the size filter you are currently running.
For this particular tank with fish you mentioned,,,you would want a filter capable of filtering/moving ,six to eight times the volume of water the tank holds each hour.
Example...55 x 8 = 440 gallons per hour.Filter material will need to be cleaned frequently in old aquarium water that you take out during water changes(not tapwater), or... you can clean it in dechlorinated water in a bucket.
Just swish the filter pads,sponges,cartridges ,etc around in the water and stick em back in. Replace the filter material only when it begins to fall apart ,and only replace half at any one time. Can replace the other half the following week.
