Hi, I have a 45 gallon aquarium that is fully cycled (fishless) and stocked with (now) 10 neon tetras, a 2-3" bristlenose pleco, 6 rasboras, a small piece of driftwood for "pleco" (that's also the name my wife and I gave him...LOL) and a few live plants. I've had this tank stocked for about 4 months now and the fish all seemed quite happy and peaceful. I'll mention that in the past few weeks, I have noticed a neon (not sure if it's the same one that died) that was kind of hanging out on his own but he appeared to be acting fairly normal and looked to be well-fed like the others. Well, out of the blue the other day I noticed a dead, half eaten neon. All of the other fish appear to be schoaling together and acting normal. I haven't checked the ammonia/nitrate,nitrite levels lately but it's kind of concerning things may be going downhill. I only feed the fish once a day, do about a 30% water change once per week and dechlorinate the water prior to adding. The water temperature is a consistent 78 degrees F every time I check it. Thanks!
