| Do you have current water parameters on the 5g tank that has the sick guppies? Do you have a picture to post that could be used to confirm fish tb or a different illness? Part of the problem is that tank is EXTREMELY overstocked. Basically, you have enough fish in there for a 35g tank, so the bioload is overtaxed to about 700% of what it can handle. Being that overstocked makes it much easier for the fish to get sick.
Your 20g and 30g tank are also EXTREMELY overstocked. The guideline for the smaller fish is 1 gallon per adult inch and with cichlids, usually a 30g holds 5 of them at the most.
