Neon Tetras Vanished!

So I have a 29 gallon and started out with 2 silver tip tetras and 6 neon tetras.

After awhile I added 6 more silver tip tetras to make 8 and 3 green/bronze corydoras.

I was going to wait some more and then get three more corys and 3 more neons but two disappeared!

I found a neon the morning after I had gotten them in the filter and they were all doing fine but a couple days after getting the other fish I'm only seeing 3 neons...

Did they die and corys ate them? What happened? I don't want this to happen again and all the fish have been doing good up to this point, should I not have neons in this tank?

Thanks for all the tips and suggestions, guys and gals! I really appreciate it!

neons are sensitive things. maybe adding too many fish at the same time killed them as the filtering system can handle the load just yet and the ammonia must have spiked.

If they were eaten, you should see some skeletal remains unless they were small enough to be swallowed whole (doubtful unless you have larger fish)

Is it possible that they're stuck in some decorations?

I found one of my cories stuck under a rock that I was using to raise ph. The hole that he was in didn't look big enough to put my finger tip in but he managed to wedge his way in there.

Animal testing is a terrible idea; they get all nervous and give the wrong answers.

Neons are extremely hardy IMO.... I've never had a Neon die on me except in the travel bag from LFS to my house... Had my current ones for over a year now.

mainly @ kitten

So...you won't believe this...but I now have four neons...

I knew I had 3 neons..and thought that two had vanished. I was doing a water change and took out my center piece and found the missing neon. I didn't pay attention at that time...and he still may have been hiding...but I just fed my fish and there were four!

They're a darker color now, is that good? Looks like they're more full of color.

I'm noticing now, though...it looks like their starting to get Ich...and my tank is tetras and corys...and with this you can't really treat them other than increase in temperature, correct?

Are there any other methods? I don't want to lose these guys...I think I heard of salt? If so, how much per gallon and how often do I do water changes when doing that?


Thanks guys! You've been helpful!

Salt works for treating ich I believe but I recall salt being a very bad thing for corys...There's certain meds out there for it that I believe should work

raise temp slowly...... and watch them closely. i have done this to my black neon with ich.it went away without meds or salt.i raised my temp from 28 - 30 by leaving the lights in the tank on longer.it's a gradual raise an after a few days i see their ich had dissipated

I was thinking about leaving the light on to raise the temp a little more.

The heater that came with my tank is the temperature that it is and that's it. You can't set the temperature. I may have to go out and purchase a heater so that I can raise temperatures in a case like this, also, if I want to try the German Blue Rams I need a good heater that will keep the water constant and at a higher temperature than what my current heater does.

Anyone have this heater: Marineland Visi-Therm Stealth Submersible Aquarium Heater ??
