I thinking of getting some definite yellows in my tank so im starting to consider yellow labs in my peacock hap tank. I know those ans acei are pretty much the only mbuna thats suggested in a peacock hap tank the acei are not in question i have enough blue should i do it ? Im also looking for a weekly treat for my guys and im scared to what i can give them with a clean conscience. I want to give them blood worms once or twice just on the weekends is that ok ? what else is good for the weekends ? I want maybe two or three. It doesnt just have to bee junk food it could bee veggies also to change it up every now and then.
