Hi all. I've never been on afish keeping forum that has a section for tank builds, but I love the idea. Because of this, my "build" is maybe a bit further along than it otherwise would be. The tank is 36"x12"x15" (LxDxH), and, according to aqadvisor, it's about 28gal (US). I'm experimenting with compost as a base layer, and I did intend to use slate as a mid layer, followed by gravel or sand on top, but from what I've read since, sand on its own is an adequate cap, so long as it's deep enough. This is what it looked like before adding the base layer: This is a 2nd hand tank given to me as part of a "fish rescue" after the original owner sadly passed away a few years ago. The fish were common goldfish and 1 Blackmoor. The commons went to a colleague's pond, and my dad took on the BM in my 200ltr tank (I don't live with my dad, but the tank, stand and set up were bought and paid for by me). Anyway, after leak-testing the tank, I emptied and added the compost (organic). Mistake 1: I didn't completely empty the tank, there was about an inch left in the bottom of the tank. This is what the tank looks like now: I know, I need to fix that background, (not to mention the compost) or else, replace it, but I'm going to roll with it for now. I am going to heavily plant this tank, and going to try my hand at a bit of aquascaping. I'm thinking of adding some sort of rock, or maybe some more bogwood to the centre-left of the tank, facing the wood already in there. I intend to keep some sort of dwarf cichlid in there - either German Blue Rams, or Apistogramma Agassezii, along with tetras, but I keep swinging from Ember Tetras, to Rummynoses. I was going to go for a South American biotope, but I suspect the lighting is low in this tank, and, typically, it's the South Asian plants that seem to do better in low light. At least, according to the plant site I was on. I'll be keeping this thread updated, but I'm not in a particular hurry to get it set up. I'd rather get it right, first.
