I have a 15 ltr tank with gravel and some imitation plants, and a filter and light.
questions. Is the tank big enough?, should the filter be left on at all times? should i get live plants? can i put in a couple of cold mountain minnows in the tank along with my betta?
Any help would be appreciated before i go and buy my fish tomorrow.
do i need to put any treatment in the water before adding my fish. the tank has been climatising to room temp for the last 72 hours now.the water came straight from the tap, and the filter has been running for 72 hours also.
