Anytime there is an unexpected loss of fish, water chemistry should be checked. Use a home test kit ( https://www.petco.com/shop/en/petcostore/product/api-freshwater-master-test-kit# ) or submit a water sample for testing. Most pet stores will do this for free or for a small fee. Confirm an absence ( 0 ppm ) of ammonia and nitrites with a nitrate level of 20 ppm. pH can range between 6.5 and 8, water temp should be 65 F to 75 F. If chemistry and water quality are within normal parameters, then illness or aggression would be other reasons for the loss. It is always recommended to quarantine fish in a separate tank for 2-4 weeks prior to adding them to the main tank. During this time, they can be treating for infection or parasites. I am sorry for the loss of your fish.

Water conditioning can be complicated and I recommend to stop by your local aquarium store. They are most often familiar with the local water quality and can give recommendations specific to your location. Some areas need buffering solutions to help control things like the water pH. Here are a few links which may help answer some of your questions about water condition: https://www.aqueon.com/articles/freshwater-aquarium-water-quality https://www.petcoach.co/article/aquarium-water-management-alkalinity-vs-water-hardness/ Before moving your goldfish, make sure all the conditions are appropriate for goldfish: https://www.aqueon.com/information/care-sheets/goldfish https://www.petcoach.co/article/how-to-help-your-new-goldfish-thrive/ I hope this helps and please feel free to post any additional questions.

These catfish, and most fish, should not be handled frequently if at all. They have barbs, for self defense, that can injure you. If you must handle them, wear gloves and gently scoop them up from underneath. There may be some concerns keeping all these species together in one tank. Arowanas get very big and require large tanks. They can also be quite aggressive and may go after the Discus and Angels. The catfish, being a bottom dweller, may be safe. Another issue may be water hardness. Discus and Angels come from soft, acid water while Raphaels prefer hard water. Also, the Aro, Discus may do better in warmer water than the Angels and Raphael. These are all impressive fish and a joy to keep, but you consider the natural environment of each species before placing them all in the same tank.

Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. High ammonia levels, PH imbalances may be responsible for that. Oxygen concentration and quality of the filters should be determined as well. Lack of oxygenation could be the cause of it. If water quality is good and there are no major imbalances, Bubbles should examined to look for any sign of bacterial/fungal infection and eventually water should be treated. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

It sounds like you need to take a trip to your local pet store. The clerks there can help you pick out an appropriately size tank with proper filtration and heating that can help keep Sushi healthy. They can also let you know what water treatments you'll need for the water in your area, as well as test any water you bring it to see if it is OK for Sushi to live in. Pet stores will also carry commercial goldfish food which is a balanced diet that is given to them. It should have feeding instructions on it so you know how much is appropriate to give to Sushi.
