How many Gouramis and Rainbow fish can I have in a 75 gallon aquarium with 10-20 smaller fish (tetras and danios)?
I have a 75 gallon tank that I am cycling. I am upgrading from my 20 gallon. I already have a common pleco, 2 danios and 3 tetras. For smaller fish it's easy and safe to use the 1 gallon per inch of fish, but obviously it's different for larger fish (please don't tell me to disregard the rules, I don't want to overcrowd my poor fish just to get a certain look). I've never had fish bigger than Tetras and would like to give it a try. I was looking into adding gouramis, rainbowfish, and some more danios and tetras . I was hoping to get recommendations on how many gouramis (dwarf and up to 8'') and rainbowfish I can have with maybe say 10-20 small fish(tetras and danios). I also read that swordtails, rasboras and barbs are good with tetras and gouramis, so I hope to get some input on these fish too. Thank you
