After months of researching and fishing, Someone has told me and even sent pictures of a place near me with small bowfin. The only problem is that they are much smaller than I wanted. Because of this, I cant put them in my 60 gallon or pond because they would be eaten. Do yall think that three or four 2-3" bowfin could live in a 20 gallon long for about a month and a half? It would be temporary until im done building my second pond. A 20 gallon long would be about as much as I could afford right now and still be able to get a nice filter for the tank( im assuming they are messy). Also, how often should I feed them? I am planning on feeding them bits of worms and guppys once a day. Is that to much or too little? Another thing is that I plan on having the tank planted with brazillian elodia, which is alot like hydrilla. If yall could answer these questions and/or give me some tips It would be much appreatiated.
