I have a 29 Gal with 1 blind cave tetra and a 6 glass catfish (k minor). I want to get some loaches next and last and I was looking at Botia Angelicus (aka Burmese Border Loach/Polka dot loach) Does anyone know if these fish will get along with what I have? I was planing on getting 3 or 4. Do I have enough room? Thanks!
