About a week ago I posted about moving miyagi to a 5 gal...he has changed sooo much. Prior to the five gal he was in a squished lightly planted 3 gal...he was sooo spooky...it was hard to work around his tank, I always worried about him flopping out during cleanings and feeds when his cover was removed et....I moved him to the 5 gal planted extremely heavy with silk plants and terracotta hidy houses and he is so different. Its amazing. He's calm and actually visits with me now. He feels safe and secure. I def recommend 5+ gals for plakats! im just amazed by the dramatic difference.
