Exclamation Sick Betta!

I just purchased a new tank: because I wanted my betta to have more space to swim.

Unfortunately, after i purchased the tank (two days ago) it starting lying on the bottom of the tank. Is it possible the filter on the tank is too strong for him? I also added two tank mates when I bought the tank. A small bristle nose sucker fish and a snail. I've noticed the bristle nose produces a lot of waste but I read that the filter for the tank is really good, so I wasn't too worried about it. Should I be?

Here's the info from the sticky:

What size is your tank? 3 gallons
What temperature is your tank? 76 to 82 degrees
Does your tank have a filter? yes
Does your tank have an air stone or other type of aeration? no -- just the filter which aerates the tank
Is your tank heated? yes
What tank mates does your betta fish live with? snail and bristle nose sucker fish

What type of food do you feed your betta fish? pellets and occasionally blood worms
How often do you feed your betta fish? every other day -- 3 or 4 pellets and occasionally a blood worm for a treat

How often do you perform a water change? Just bought the new tank two days ago
What percentage of the water do you change when you perform a water change? N/A
What type of additives do you add to the water when you perform a water change? A water equalizer

Water Parameters:
Have you tested your water? If so, what are the following parameters? Unknown


Symptoms and Treatment
How has your betta fish's appearance changed? Color slightly muted
How has your betta fish's behavior changed? lying on its side on the bottom of the tank. However, it still is producing bubbles and has moments of swimming just fine. Eating is normal.
When did you start noticing the symptoms? Yesterday.
Have you started treating your fish? If so, how? No
Does your fish have any history of being ill? No
How old is your fish (approximately)? Purchased a few months ago

I would really appreciate your input! Thanks so much!!!

Did you rinse the tank before putting the fish in? Is the ammonia spiking (this can be a problem, especially with the bristlenose)? Did you acclimate the betta before putting him in?

If the filter is too strong, then you should be seeing your fish struggling against the current (think a tiny person fighting against a strong wind-- and failing :) ) If he's able to rest, then I don't think that's the problem.

Maybe he's stressed from having to deal with a new tank and new tank mates at the same time but I think someone else will be able to give you more of an expert opinion.

Thanks for your post! I did rinse the tank and acclimate him to the temperature. He seems to swim fine around the tank, if he swims right in front of it, it will push him down, but nothing that stalls his swimming. I hope it's just stress -- poor little guy.

Your probably over loading the bioload on the tank. Generally I've heard nothing with a betta under 5 gallons besides maybe a small snail. Also I've heard any form of water disturbance on the top of the water is bad for bettas. So if your filter pours into the tank you'll probably have to baffle it with a syrofoam cup or something. Once again I'm just relaying what I've heard. I generally dont mess with filters other than a sponge filter (with one or two bubbles a sec). I'm sure someone with a better knowledge of these things will be along.
