how often should i do water changes and how? meaning what percentage for what day (25% on first day.. etc) also i was thinking about dropping a bulb or two in there to try and grow live plants.. is this a bad idea? and also i need to get him a heater.. will a 7v be too much? its for 2-5 gallons and some of the reviews on this
heater said they use it for their 1.5 gallon i just have to unplug it on hotter days. i dont have the money to move him to a bigger tank right now. i thought 1.5 wouldve been sufficient.
