Thought I'd might as well post an update of my current stocking. Tank is 450L (too small for full size specimens, but will do for now). Stock is 1x Cuban female (20cm), 1x red oscar (30cm), 1x jag (12cm), 1x super pretty convict female (<10cm), 1x longfin senegal bichir (20cm), 1x delhezi bichir (25cm), 1x palmas buttekoferi bichir (25-30cm).
Tank receives 50%-70% waterchange weekly and have zero problems. Cuban likes pushing the bichirs around sometimes and frequently wants to pair with the jaguar who doesn't want a bar of it.
