Default Fish keep dying

I need help! I’ve got a 13 gallon tank that I’ve had set up for a few months, after letting the water season for three weeks we bought a plecostomus (2” right now) and three guppies who died within 13 days. We did a water test at three separate pet stores all that said the water was fine, so we got 3 Dalmatian Mollies. By the end of a month the fish were looking sick and one died, the two mollies left seem to be sick but the plecostomus is doing just fine. Any ideas?

Questions....

-Is your tank cycled?
-What kind of decor is in your tank?
-Do you know about the nitrogen cycle?
-What type of filter?
-Is your water heated?

I recommend buying a liquid water testing kit... way more accurate than the stores.

The stores often use the same test kits that they sell, though.

Here in the UK they tend to use the brands that they sell.

Iíve never had too much success keeping Mollies to be honest ... and Plecs are air breathers and are slightly more forgiving..

Thumbs up For what reason do my fish continue passing on?

There's nothing more disappointing for a fish proprietor than investigating your aquarium to see one of your fish coasting dormantly at the surface.

It very well may be considerably all the more disappointing if throughout the following scarcely any days more fish begin to drop dead, leaving you thinking about what is making them bite the dust and whether you have accomplished something incorrectly.

In the event that you have lost a couple of fish in a short space of time it could obviously be an incident. Numerous types of fish just live for a year or two overall, implying that passing is unavoidable sooner or later.

In any case, it merits watching out for the circumstance on the off chance that there is something in the aquarium that is making the fish kick the bucket.

My bet is that the tank never cycled until the fish were added. You can't leave the tank to "season" it needs something to start the process, be that basic ammonia, a hardy fish, or some dedicated "tank starter". The problem with using fish is that the cycle is affected by the bio load. Add another fish and there will be a small new cycle because the bacteria can't cope with the increased load.

My reef tank that is now 8 years in the running was started with neat ammonia, and the cycle lasted around 6 weeks. I used salifert test kits, and I would recommend them.

Yep agree with Malc, tank likely isnt cycled, Or if you had some tank start in etc when you changed the water did you use a tap safe type chemical, or another common one, if you washed the filter during a water change did you do it in fresh untreated tap water?

Tap water will test "fine" for fish. If you put tap water into the tank and leave it, it'll stay as tap water the same as it would in a glass.

You need to start the cycle, one of the easiest or cheapest ways is to just throw a bit of fish food in, it'll sink to the bottom and rot - creating ammonia. It wont be as fast as using neat ammonia but it will work.

Leave it about 3 or 4 days and test for ammonia, you should have some showing and your cycle has started. Then its a case of waiting for the cycle to complete before adding your fish.
