I have a 2 week old tank, (125 lits), put 3 guppies in after 6 days, and then after 11 day put 2 mollies and 2 platys in to the tank...... Have noticed today that the mollies and platys are going to the surface alot.....
Id this usual or do they need more oxygen?? if so, HOW DO I GET MORE IN TO THE TANK?? am really worried.....
So far, tested water twice at LFS and water is good, done no watcer changes so far. The tests said that there were no problems.... Look Im nes to this, have read the books and the treads, but forgive me im still a novice! any ideas.....?
