hey guys i think i MIGHT have found out why my red eye tetras are inactive. everything on the tank is perfect. no ammonia, no nitrite, and only about 5-10ppm nitrates. the temp never fluctuates. the other fish in the tank are acting normal. but a few of my red eyes dont move much. only like 2 of the red eyes actually act normal. but my tanks temp is at 80.5-81 degrees F. and im thinking if i lower it to about 76-77 they will do better. what do you guys think??

btw they are all eating like pigs and usually swim around for about 5 min after feeding before calming down.

the other tank mates are serpae tetras and xray pristella tetras. they are doing fine.

yeah well im lowering the temp because i read that fish arnt as aggressive at a lower temp. and they seem to be swimming around more today. also i only have like 3 large plants in the tank and i might get a couple more.

reason i think its aggression is because one of the red eyes likes to chase the others around. also one of the red eyes has a gash on his side.

For example, 1 tiger barb will attack just about everything else in your tank. 8 tiger barb will fight amongst themselves and leave everyone else alone.

2 serpae tetra (these are rather aggressive tetras) will attack your other fish, 6-10 won't.

So that's how using stocking levels will keep aggression down.

What I mean by using tankmates is to place only fish of similar temperament together or fish that inhabit different zones.

For example, a green spotted puffer is quite aggressive, but it will live just fine with a cory because the cory just stays on the bottom and the GSP inhabits the upper part of the tank.

thanks for the video. and im thinking its one of two things. its either an aggression issue or they are really shy and still need time to get used to the tank.

As long as he comes out to eat that's fine. My blue chormis population has slowly died off until for the last 3 years or so I've just had two. They are happy and healthy, but hide all day until about an hour before feeding and an hour before lights out. But as long as they are eating and healthy I will let them hide.

They do it because there isn't enough of their kind for them to come out.
