My new 90gal tank is still cycling and I'm now getting worried about the fish that are already there in it (6 angels, 10 lemon tetras, 6 bleeding heart tetras, 2 bala, 2 rainbow sharks, 6 snails, 2 blue gourami, 2 golden gourami, 2 pearl gourami)… 3 week up… 2 weeks to go… Also have 3 pcs of driftwood, a plant, a lava rock and some big white rock like slabs. Need to do some minor water changes… I’ve maintained 27-28 degrees and 2 filters which I alternate and use… if I put both filters ON then all the fish fly from one end of the tank to the other and back…
