tlindsey even If I spread the food around? or over feed so the bush fish get full then vacuum the rest up after the knife eats?
You could try that but maybe jeopardizing your water quality if uneaten food isn't removed.
lol that won't work the Ctenopoma would suck up the food with a blink of a eye.
the knife is faster than the bichir as far as eating goes... it’s a night time fish mainly... mine comes out to swipe food... my bichir are pretty darn slow to eat....
i can not speak to the brown knife as i’ve only had the afer which i understand is more aggressive.
i’d listen to the others if they are concerned about it being out competed for food...
i’ve only had this african bio tope running for 3 months or so now in a 5’x18”x24” -
i’ve only had the previous mentioned problems,
the Ctenopoma may be a good idea -
GL!
