Yeah it was, it was like an addiction. Keeping so many though puts you on a knifes edge between success and failure, and in the end failure caught up hard. That's why I made the decision to return to shrimp, that and I just plain missed keeping them. I have a compulsive personality though, I don't do anything by halves.
I learned from my mistakes last time around though, so have built my tanks to avoid repeating them. Little things like not using ANY plant ferts or CO2 in my shrimp tanks that can go wrong. I did learn one more lesson though, not to use under-substrate plant substrates in soft water tanks... Turned out the one I did use contained a source of calcium.... Knowing what I do about plants, I should have suspected this as plants use calcium to fix nitrogen from nitrates. Good for freshwater tanks for neocaridina and snails though luckily, so only had to tear down the 1 tank out of the 3 I used it in. lol
