Back from my holiday and have arranged to take delivery of my new Juwel Rio 180 early to mid next week. I'm really looking forward to it!
Originally, I'd planned to do a fishless cycle with this, but recent developments have complicated matters (in a good way I hope). A friend of a friend is moving house and running down his current tank prior to dismantling everything and setting up again at some point in the future. He has offered to give me the old mature filter medium (lives only 5 mins away, so easy transfer etc.) but would like me to take 8 of his fish and rehome them in my new tank.
These are Silver Tip Tetras – all looking healthy (he's had them for about 6 months) – 3 males and 5 females (we think) who all seem to be fairly non-aggressive and haven't bothered his other fish.
So, my questions are:
1. Can I just fill up my new tank and (after running for 24 hrs to heat water and check for leaks) use all of his mature filter medium to put these fish in immediately?
2. I wouldn't put any more fish in for about a month, but had some plans as to what I was eventually going to stock:
cory cats
cardinal tetras
Will the silver tips be OK with these? Not sure about what else, but wanted to have a larger fish/fishes to set these off. I thought about gouramis, but would worry about aggression towards other fish. Does anyone have any advice on which larger fish would be Ok in this set up? I have soft water.
Thanks in advance
