Hello Again! So lets get straight down to business. Aquarium is 10 gallons. Was thinking of getting 3 dwarf puffers (1m 2f) Heavily planted with a lot of plants that are native to where they are. Filter.....Was thinking about a 20i Tetra Whisper Filter Heater... One that is a grade higher then what is recommended (saves on power) Thinking Marineland since I've had good luck with them. White Gravel so far as substrate goes as well. So what do you think? Suggestions?
