They were mainly guppys... :)
About what I want to put in there now, I was thinking about less quantity, more "quality", as in color and size.
I can't really do it before taking it indoors because... it is indoors. I live in an appartment on and 8th floor. :) Somebody's gonna get wet... :P
All those years ago I read that before putting the fish in, we should get the tank up and running, all set, with heater, filter... all but the fish, and keep it on for about two weeks.
I always did this when starting the tank and that was my intention now. What do you say about this?
About the seams, I think I'll look for the right silicone type and do that.
Those 400 fish I mentioned, most of them died back then, because the tank, which was homemade, had been sealed with standard silicone, which of course, was toxic.
When we found out, we moved the remaining fish and had the tank resealed by a "pro". I hope that won't be the case now... :)
