As stated in another thread i am considering getting a Bichir for my 55 gal tank,i want something different and predatory.I will be doing some studying up on these fish but could really use some help from you guys.1st what is a good Bichir for a 55 gal tank??2nd can they be housed with large Silver Dollars??3rd what do they usually eat??4th how big do some of these guys get??What kind of ph do they need??Are they "escape artist??"I will probably have to order 1 online because the best LFS in my city never carries these guys so my species availability is really limited.I will let you guys know what species are available to me.Thanks
