oh =( well what do you think would be an awesome fish to house in a 55G? just a single MEAN fish (I am returning my oscar, RD, and Senegal Bichir because i didnt do proper research before i Purchased) =( So I will have an empty 20GL and an empty 55G
The ratio for frontosa from what i have heard should be 1 male to 4 females and the double nickel is to small for that. For a single fish I would try a green terror.
