Wouldn't the tank tipping over be more danger than the stand failure? How can you secure the tank? Most stands are designed to hold the tank up with the weight on the top holding it in place, not from swaying.
What did you do with all of them? How dark did they get? Interested in starting a colony of Calvus and the Black Congos Look real nice. Just moved and am starting all over. Nothing in the Portland/Vancouver area.
I know this is an old post but I am interested in Calvus Black - Congo and wonder if anybody has any. Starting my tanks back up after moving and am wanting something different.
