I am inthe best petshop its half sn hour drive from my house and they hav an albino birchir and a zigzag eel and gt and at home my tank has 9 tiger barbs 3 convicts 2 firemouths and 2 salvinis could i get a gt and a senegal or zigzag ??
If the Senegal is big enough you could do that, the gt would probably be bullied since territories in the tank have been claimed, and peacocks... Although readily available not a good beginner fish, require special feeding practices and needs sand. Usually just hides all day anyway
IMO I wouldn't get the bichir for reason being is all the fishes you currently have are fast eaters and your fishes probably wont even let the food hit the ground. Polys are slow when it comes to eating. They dont look for food, they sniff it. So as long if your able to continuously feed extra and making sure the bichir eats then your good, but other then that the bichir is in no way competition...IMO...
