Silvertip Tetra behavior question

I've recently set up a 20 gallon tank for some tetras. I let the water filter for two weeks, with my betta living in it, just to give it a start. I've also planted 6 live plants in it. Five days ago, I added six silvertip tetras to the tank. After a day a two, the tetras had defined their own areas with two tetras being on the lower end of the group. The only time I'd see all six was during feeding or if I really looked around at all the hiding spots. I also added 6 cherry red shrimp to the tank two days ago. They all seem to get along fine. Today, after a partial water change, the tetras started acting weird. They are all out and swimming just below the surface and gasping air. I only changed out two gallons and the temp only changed by +.6 degrees. The shrimp are being more active also. I changed the filter on my water filter thinking it may have been clogged. The fish are swimming upright and there is no redness by the gills. Is this something I need to be concerned about? Or is this just new behavior? Or will the new filter take care of it? Any ideas or help would be appreciated.

Did you add water conditioner to the water before adding it to the tank?

I added conditioner to the tank after I added the water. They all seem fine this morning. I think I overfed them and clogged the filter. I have flakes, small pellets, regular pellets and bloodworms to feed them. I've been putting some of 3 of them in each time I feed them, so twice a day. Time to cut back I think. They aren't attacking the food like before either. It's been so long since I've kept fish, I think I overcompensated on the food!!!!

I would suggest that you condition your water before adding it to the tank, if you are adding tap water. Chlorine and chloramine that may be in your tap water can harm your fish. The water conditioner eliminates both of these chemicals immediately making the tap water safe for your fish:)

Sure, take the easy way of filling the aquarium ( Using a hose connected to a valve on the faucet) away from me!!!!!!!!!!! LOL Well, at least I can still use it to drain some water, then I'll use jugs. I'd rather make a few trips than shock the fish!!!!! Thanks for the tip, I'd of kept on doing it with the hose.

When I do water changes I add the conditioner to the tank first and then turn on the hose. I never have problems doing it like that. The conditioner treats the water immediately so if you want to continue doing it like you have been just make sure to put the conditioner in the tank first where the hose is sitting then turn on the water from the tap.

Agree, there isn't (or shouldn't be) a problem starting the tap water flow and then adding conditioner; I've done it that way for over 15 years. Of course, in a small tank this could have a quicker impact. I use a pail for the new water in my 10g.

The behaviour you described indicates something in the water bothered them. Chlorine/chloramine, ammonia, nitrite, nitrate, a significant pH change, heavy metals, or any toxin. Try to think if any of this could have occurred. Temperature fluctuation so minimal would not cause what you described.

Thanks for all the advise!!! I think I'll add conditioner to the water after I drain and before I add with the hose and see how that goes. I'm thinking their behavior was caused by inadequate water filtering and flow caused by me plugging the filter by overfeeding. At the most, it was a temporary thing that seemed to be corrected by the next morning. Thanks again everyone!!!!!!!!!!

Good to know. I did wonder how people used the hose setup, but my tank is only 20 gallons so I just filled up several buckets and conditioned the tap water in them before adding to my tank. When adding the conditioner to the tank first, how much water conditioner do you add? Enough for the water in the whole tank, or just enough for the amount of water you add?

I just squirt in sufficient for the approximate gallons I am refilling. I have recently been experimenting with a different (to me) conditioner that doesn't have a squirter so I have been measuring it with a teaspoon (1 teaspoon per 10 g) so if I drain half the 115g I assume that is probably 50g max and add 5 teaspoons. When I was using the squirt container, I probably overdosed. While this is usually said to be irrelevant, it is still chemicals going into the tank plus a waste of money to overdose. Many of these conditioners also contain substances that provide/protect/repair the slime coat, and here again I cannot think that too much of this is going to be good.
