Well, I tell you what, those shrimp never had a chance at a good life!!!!! So, you use one type of animal that was horribly caught in a net, killed by sufication and then frozen... WHAT is the diffrence?
this is meant as a sort of joke BUT what makes one life more valuable than another in our hobby?
Me, I use damsels. I always have and always will. I have only lost very few in cycling a tank. A cycle, if done correctly, will have a very small spike tat most fish can handle. It's the pepole that rush a cycle and do no water changes during the cycle that have a problem. When I start a tank. It takes about 2-3 months before the last level completly goes to 0. I prolong them and do frequent water changes. I like to let the nitrogen cycle mature slowly. I have had better results and longer life in my tanks using this techniqe. So, it works for me. Than agiain, I have set up over 15 tanks so, it took a while to get it down to an art for me.
