hi, i have 14-15 4 week old gf fry in a 5 gal tank, half filled with water. I need to move them to another tank because the one they are in has a crack half way up the back of the tank there for I am unable to raise the water and i would like to add a filter to help keep their water clean. Right now they are in 2 to 2.5 gallons of water. I siphon their tank everyday. Is it ok for me to use a net to transfer them to their new home? I do not know how sensitive or fragile their fins are.
Also, how long can i leave an algae wafer in their tank. According to the hikari algae wafer package it says 2 hours.
thank you
karla
