This is just my opinion as unpopular as it may be. When as monster fish keepers are we ever just happy with what we have? What is this concept of what you gonna do in two years? These are not arapaimas nor shamu..... These are bichirs. If you want more bichirs, get em! ...... But as someone here mentioned, do expect to do more water changes and maintenance. I love doing WCs so its no problem. A 24" by 4ft aint a bad size tank for your bichirs..... This isn't like putting an adult oscar into a 29gallon. Get more. Enjoy fish keeping. Don't be afraid to experiment. Think out of the box. You worried about what you gonna do in 2 year?..... You never know..... You might not even be into fish keeping! So get them bichirs..... Do your thing!
