I've had a 29 gallon tank set up for several years and now I'm looking into getting a much larger tank, but I don't know what equipment I need. Several months ago I bought 3 tiny silver dollar fish and then as they quickly outgrew my black skirt tetras, I realized they're going to need a bigger tank. They seem happy and hang out with the tetras and enjoy eating every plant I consider putting in. The tank is pretty heavily stocked w/ about 15 neon tetras, 3 blk skirt tetras, 3 Cory cats, a pleco (kids convinced me again, but they usually die on me), a snail, a couple ghost shrimp, and the 3 silver dollars. Everyone gets along well and water tests come back fine. If it makes any difference, I probably wouldn't add much to a larger tank.
Right now in the 29 gallon tank, I have the heater, a marineland 50 gallon hanging off the back, couple airstones, and UV filter. But looking at bigger tanks (90-125 gallons) it appears that's not going to be sufficient and I have no idea what's necessary vs just what others are putting in because it's 'super cool'. I do plan on continuing to try to find some plants these guys won't destroy, but don't plan to add CO2. What components do I need?
