Just signed up and looking forward to reading and learning about this great hobby. I just recently purchased my fist tank off the internet. I am going to be keeping 2 Oscars and a Wolf fish. I will be placing them in a100 gallon tank with a Eheim wet/dry filter. I feel so badfor the Oscars and Wolf because they are in a 20 gallon tank right now and have no room to move. I have so many question but will post them in the right threads. I look forwad to talking with everyone.
