I have two pairs or mpwimbe blue frontosa that I need to move approximately 4 1/2 hours. I wouldn't normally care too much but these happen to be F1's and I really do not want to hurt or kill them. I also have a wonderful Royal plec that is about 10" in length. I really do not know how to keep heat and aeration on them for that period of time. It actually may be more like 6 hours by the time I get new water in the tank and get things going. If anyone has any experience please let me know what I should do. Thank you to all of you.
