The width will limit the tank size. The largest tank would be a 25 gallon tank. If you choose this size, make sure the stand can support upwards of 300lbs. That is what the tank will weigh once filled and set up.

It's not really recommended to keep fish in bowls with no filtration. And 2.5 gallons isn't really big enough for much. A Beta fish may possibly do ok in it if you can maintain it. But I would recommend more doing plants and a few snails or ghost shrimp type of animals in a bowl that size.

The bowl looks definitively a bit small for the two fishes. To understand exactly what is going on you need to approach this problem radically but logically. Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. Clinical examination should always include a water quality check, even if you have done so already. Water testing should be performed with a quality test kit, measuring NH4, NO2 and NO3. High ammonia levels, PH imbalances may be responsible for these signs. Oxygen concentration and quality of the filters should be determined as well. If water quality is good and there are no major imbalances, your fish should get examined to look for any sign of bacterial/fungal infection and eventually water should be treated.

Here is a helpful link: https://www.aqueon.com/information/care-sheets/goldfish Your local aquarium store will likely carry a powdered product to add to the water to increase the pH. The package will have dosing instructions. I hope this helps and please feel free to post any additional questions.

Depending on the number of fish you get, water quality will be the most important factor in maintaining their health. You'll need quite a large filter for a tank that size. Ideally, choose one that is rated to handle at least twice volume of water in the tank. Mechanical, chemical and biological filtration are all recommended as well as the inclusion of an ultraviolet filter. Silver perch are hardy and can tolerate a wide range of water parameters but thrive at temps between 23 C and 28 C. You may need a heater or heaters capable of maintaining that range. They will spawn anywhere between October and April depending on the age of the fish. Mature fish will spawn early, between October and February, while younger fish will spawn late winter into early Spring. They are an omnivorous species but do well on a commercial pelleted fish chow. One suggestion would be to contact local owners of fish ponds, pond builders and large scale breeders to get more detailed information and to see operations and set up in person.
