Gee, Bill...I thought he meant his fish named Oscar :roll:
Few things:
-too many fish too soon, not good
-new tank needs to cycle (as was pointed out, you can read about it here)
-try to learn what fish are compatable, NOT all fish are
-read, read, read
-remember sometimes that cute little fish can grow into a huge big fish
-don't be so willing to believe everything that pet store people tell you (not to say that all are not good, but some just don't have the experience/knowledge)
-all though the more experienced people may not require the use of test kits or regular water changes...we as newbies...these are good things
-watch your fish...feeding is a good time...get to know their behaviour, their color, their shape, etc. ....that way, the more you know these things the more you'll know if something is wrong
-ask questions, there is no such thing as a stupid question, asking is how we learn...and you will see that the people here are always willing to help & have lots of experience and knowledge
-you will find that, as in most things in life, there will be differences of opions...but that's also because what works for one, may not work for another
AND...it is sad...BUT...sometimes no matter what we do, we will have fishies die!
And don't forget as Bill pointed out...let us know more about what you have!
AND LASTLY...have fun, this is a great hobby and remember the people here are fantastic...I'd be lost without them!
Take care,
Caper
