HI everyone.... been reading up a bit on freshwater and have finally decided to take the plunge. Iam in dunnville ontario. so far have a 400gallon reef tank and an 800 gallon fowlr both obviously saltwater. New tank i picked up for a private dining room is 1800 gallon and i plan on using it for freshwater. Would like a couple bd rays tons of colored smaller fish( possibly cichlids) a fly river pnt, cross river puffer, albino sturgeon,some nice rare plecos.... need some advice on what will work here. thanks so much
