I have a 55 gallon community tank with gravel and I want to resubstrate the tank to sand and keep 4 black skirt tetras a pearl gourami in the 55 gallon and move all the other fish to a empty 29 gallon tank and add a Senegal bichir a leaf ctenopoma and a electric blue Acara and a blood parrot cichlid to the 55 gallon. Would that work? Add any suggestions.
