ok i've fallowed this entire thread.....and i think it could have been summed up in two posts.....but there are 14 pages of it!
My advice right now is:
1. raely covnenrate on te splling n graamer LOL
really concentrate on spelling and grammer.....its really hard to read through so many posts of mistakes like that.
2. A 55 gallon tank will be fine in your room. you really never have to worry about floors until you get to triple didgets, but with weak floors like you seem to have, i wouldn't worry about it even with a 75 gallon tank.
3. Seriously, i don't know how your fish breed....but then again i don't see how the oscar i rescued is still alive either....
