Ok, I'll stop adding the chemical then. Probably was no point to adding though, because pH was 6.9 prior to adding it the first step. And I've taken your guys' suggestions and tips and it does seem to be working out. Just tested the ammonia and it read .18 which is a .7 drop from the other night.

The fish also seem better off, both more active, eating normal once again etc.


Thanks a bunch everyone for your time and input!!

Just a quick/update question. I've noticed while watching TV with the lights off, my fish become more active. It seems as though as long as the aquarium lights are off, they swim more, and they seem more apt to eat.

What's weird about this is that I haven't changed anything about the lighting. Still using a 18" 20w 4600 light.

My ammonia levels are about .1 ppm, still working on getting that down, making progress. But what would cause them to become nocturnal like this??

Most of the tropical rainforest fish we keep in aquaria come from waters that are not bright but heavily shaded by overhanging trees, aquatic vegetation and so forth. I'm not familiar with the specific habitat of rainbowfish, but from a quick search they seem to originate from a variety of habitats including jungle streams and swamps, so this fits in. Bright light would not be a preference of rainforest fish, and aquarists often shade the tank a bit with floating plants like Ceratopteris. If your tank is a 16g and you have one 20w tube, that is not overly bright (close to what I have at 1 watt per gallon).

A second observation is that when the tank lights go out, fish are normally more active just from the "shock" of the sudden darkness (by comparison). It is always good to have room lights on when the tank light goes out, as the fish will be less startled and more relaxed. I have sometimes remained in front of my tanks after the tank light is outwith the room lit, and generally there is very little activity; once the room light was not on and the fish were darting around quite a bit--which only proves that the room should not be dark when the tank light goes out. In nature, there is no sudden day or night but a gradual darkening in the evening and gradual brightening in the morning. Fish are more relaxed when we can replicate this a bit more.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Ahh ok, that makes sense then, pretty logical. On reason I mention it is because I never noticed it before this. So, just my fault. I just picked up some anacharis with the plants the other day, maybe I'll let one or two strings of that float around some.
