Hello everybody, neebie here.
I just started the hobby doing a fish in cycle (on purpose) in an 10g with a young guppy. After 4 weeks the readings of amonia and nitrites are 0.
Now that my tank is fully cycled I'm planning on getting more companions for my lone warrior. And I have been reading that you MUST have a heater for your tank, but the problem is that neither my LFS
nor I have a heater and it just seemed odd to me.
I live in central America and the weather here is always warm.
Although I don't have a heater my guppy fish seems happy and healthy.
●¿do I really need a heater?
●¿I could harm my fish if I don't have a heater? Any sickness stress or something.
●I have plants hornwort and jungle val ¿does it affects my plants?
