I really love the BGK and my dad had 2 when i was young in a community tank and aggressive to semi-aggressive tank, and both did well. (it was a 55 u.s. gal) I plan on buying a not-so-much ‘baby’ BGK, but more so smaller one (small for now at least, as i know they can get large) that the private owned strict (Strict as in intense care extremely well-maintained tanks, setups, etc.) fish store i go to is selling. I was just wondering if for its size now it would be OK to have it in a well maintained 40 gal. until he grows excessively? (after that its to the 55 for him. still needs to be set up but there’s still much time before that comes into play) I know all their needs, care, etc.But was also wondering if while being well fed on a regular basis in the 40 gal and being a timid-to-other fish even in a larger 40 gal with a lot of room; would be alright to have 1 dojo loach, 1 clown loach, 1 med-small, yet hold-her-ground angel, 1 shark cat, 1 khuli that hides under lava rock all day, 2 giant danio’s, 2 Buenos Aires tetra, and 1 poor neon. (The shark ate the other 2). Yes most likely all you fish hobbyist are saying this is over stocked, but if you saw it you would even say it still is very open in there. And yes also there are caves, and a clear “Ghost Viewing” tube ready. ( the tube that is, the caves are beautifully placed hiding areas that appear as natural can be. Just please no put downs or hating, if you really saw it you would understand. I just need to know if the tank is substantial enough for a while until his growth really picks up. And also if the mixture of fish would be alright. I know a lot of successful aquarium hobbyists (including my dad) who have had these fish with BGK in similar conditions and had no problems, but then some who would whip you if you even asked if a BGK would be alright with a assorted species of ‘community/assort. tropicals’. Oh yea and it is nicely and moderately planted for the BGK. Not to little, not to much.
