Thanks for reaching out about Corn and including photos. This could be mineral deposits but is difficult to tell in the photos. Mold usually does not grow below the water level as needs oxygen. Clean the filter well. A sample of the material can be acquired and a veterinarian might be able to help by examining under the microscope. Good luck.

A small tank with one Betta will require minimal upkeep. Most small HOB (hang on back) filters will be sufficient. Tetra, Fluval and Aqueon make a wide range of acceptable filters. The tank should have a cover or hood as well as a light and a heater. Bettas do best between 78 F and 80 F. Feed 1-3 pellets once or twice daily. Change the filter as per manufacturer instructions. Rinse filter media with tank water, not tap water, to preserve beneficial bacterial populations. A partial water change, no more than 20-20% of total tank volume, may be necessary every 2 weeks to maintain water quality and stable chemistry. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Water conditioner brands include: AmQuel Plus, NovAqua, Prime, StressZyme and StressCoat. You don't need all of them. Follow the directions on the bottle. Allow the tank to cycle before adding a fish. This will allow beneficial bacterial populations to colonize the filter and substrate

Confirm it is made from a non toxic compound, such as polyethylene. Do not overstock it with fish. Provide adequate filtration and monitor water chemistry regularly. New ponds, just like new tanks, need to be properly cycled before fish are added.

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.

Monitor water chemistry using a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Pristine water quality is the foundation for healing and recovery from infection or injury in fish. You can use plain aquarium salt (NOT table or Epsom salt) as a general tonic to reduce stress, improve gill function and aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup or two of water and gently pour it into the tank. Treat for 14 days then reassess the condition. An "all in one" product, such as Lifeguard (by Tetra), can be used concurrently to treat infection or parasites. Find one in the aquarium section of the local Petco. Follow label directions carefully and remove
