I love aquariums.........my fish always die......I gave up
Next time try Convict Cyclades, You can't kill them unless your tank filter shuts down and you don't notice because the fish are hubby's responsibility and he forgot to feed them or check on them for a month. Seriously glad they are gone, they just kept breeding like crazy and they only died because the air stopped. K went back east for 5 months and I wouldn't change the tank because 55 gallons? No. So I just put in tap water when it started getting low and it was completely brown and the fish were invisible in there but as no one was floating I kept feeding them and adding water.
My FIL and MIL stopped by to visit and the light was hitting the tank just right and in the middle of my conversation with my MIL my FIL pipes up and says, "Hey, I hate to tell you this but you have fish in your Mormon Tea..." (Look it up...

)
When hubby came home and cleaned the tank there were three times the fish that we had when he left and we had over 20 baby fish living in the filter.
They WILL. NOT. DIE.
