You can try feeding them commercial fish food or meal works from your local pet store. If you would like a consult, you can provide pictures and we can give you a better idea of what kinds of fish they are and if they have special requirements for their diet. Hope this helps!

When used as instructed, plant nutrients and fertilizers designed specifically for aquarium plants will not harm aquarium fish. Allow new aquarium plants to settle and establish themselves before adding any fertilizers. Use aquarium plant substrates such as CaribSea Eco-Complete Plant Substrate http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=9087 to get your plants established faster. Seachem Flourish Advance Natural Phytohormone Supplement http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=33890 will help stimulate root growth vital for overall plants health. Even though you have plants with low to moderate light requirements, be sure to use aquarium light specifically designed for planted aquarium use (sometimes called plant lights) and have the lights on between 10 and 12 hours a day. You may need to adjust the photoperiod (the amount of time the light is on) depending on how your plants are doing and to prevent unwanted nuisance algae growth.

Thanks for reaching out about your pufferfish. Meal worms are bags of fat and should be used as treats only. Frozen thawed tilapia is okay, but no bones thus a reverse calcium-phosphorus ratio. Ghost shrimp okay, live feeder fish okay but pufferfish not super fast. Small clams or snails are a good source as also require chewing to get into. Pufferfish have dentition that can overgrow is not chewing a lot. Good luck.

Thanks for reaching out about Freddie. A curvature of the spine can displace the swim bladder making swimming difficult. Vitamin C deficiencies (scurvy) can cause spinal deformities and is usually the result of old food. Fish food should be purchased new every 2-3 months as vitamin C degrades quickly. A veterinary visit is recommended for radiographs to determine the status of the swim bladder and determine if antibiotics are needed. Radiographs might also determine if anti-inflammatories for spondylosis can help. Good luck.

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
