i have a tank with a south american amazon type theme 400 gal. 14 inch RB pacu, 4 albino oscars 7-9 inch, 2 fully grown cascadura ( strange amoured catfish) 3 misc. small cichlids and various scavenging fish but long story short i was wondering if any1 had any ideas for hiding spots for larger fish i have some pvc 8 inch elbows smaller pipe for the various small fish but decorations are very expensive in my area and live plants are in my opinion too messy they constantly restrict the waterflow of my homemade canister filter ( bucket + pump lolz)
