I was excited when I saw that this month’s Tropical Fish Hobbyist magazine had an article on the Native (and brackish!) fish, the American or Florida Flagfish (Jordanella floridae). I was, however, disappointed in some of the text, suggesting that you could keep a pair of these fish long term in a 5 gallon tank with no filter.
No. These fish are larger than Platies and are very nippy... 20 gallons is the absolute minimum for housing more than 1 of these fish (or with any tankmates). And, of course, aquariums with fish in them should have filters. That’s just responsible fish-keeping.
