i dont have the tank yet (im waiting for the petco dollar gallon sale to come back) but right now i have a baby sen and will be picking up a baby del within the week. i have them in a temp 29 gallon but as soon as i get the 40b ill put them in there. i want it to be heavily planted and havent decided what mid to top tank fish i want...i was thinking maybe angels cause i have never kept them but im not sure...what is a good compatible fish for my polys?
