i currentl have a 150g tank that i use for chiclids and a 10g tank i just started that i want to house a clown or 2 for my daughter.thank you nemo for convincing my wife to let me try s.w.the 10g tank is nthing special.the 150g is a bioball trickle filterthat'sbeen runnig for 5 years now and reallly takes care of itself.i have approx 15 african chiclids and a few tin foils and 1 redtail shark.the chiclids breed so much i've been giving away some of my older ones.(i like watching the new ones grow.if i don't kill "nemo"i'll probably take it down and switch to s.w.i don't have any experience with it but been doing my research which brought me here.so i'll apologize in advance if i ask a stupid question.look forward to learning from you
