I have a 5 gallon tank with a whisper filter and no heater. I would LOVE to have maybe a cray fish or lobster something of that nature. What suggestions do you have if any? Remember NO heater!
most crayfish prefer water between 72-76 so if you have a room that warm you should be set.i would consider a dwarf species as the bigger ones will outgrow a 5 gallon
