Mark ...sorry to hear of your losses, that just plain breaks the heart to find fish dead like that. I know how we all feel about our fish, I get super connected...I have a few that have been with me for 7+ years, others 5 years and some just a year or two but no matter how long, they become part of the family. Keep your chin up and know that you planned well adn things happen just like you said, those darn unexpected things. The tank looks phenominal in the house. I am so looking forward to my visit next week .
