Hello. Can I feed a figure 8 pufferfish live or dead meal worms? Or frozen thawed tilapia? Live feeder fish? Ghost shrimp? Thanks!
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.

I have an issue, this involves all my fish I am moving from Georgia to Utah, and of course that’s a long distance by car, but if will also restrain me from seeing my fish due to the fact that I will be flying there. How do I feed them while they’re b
Thanks for reaching out. If is a good idea to fast for 1-2 days prior to shipment, this decreased feces and will help to keep the ammonia down. Typically clear bags are utilized with about 50% water, and 50% air/oxygen used. A local pet store might be able to assist, as they get shipment in (so have older bags and boxes, which need to be disinfected) and hopefully the skills to ship. Check with the airline also, box needs to be well labelled "LIE ANIMALS" and "THIS END UP". Sometimes a health certificate for interstate travel is needed, so contact airline and State of Utah, veterinarian. Good luck.

My rainbow albino shark is slow to grab the food...now it is a little bit inactive...is this a sign where in it is under nurish...?thank you for the reply already...bless you guys...
Unfortunately this is a very generic sign and a radical approach must be followed in these cases to find the problem. 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. If water quality is good and there are no major imbalances, your Fishy 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 if you have any more questions or to discuss it any further.

Hi there! Having a few questions: i dont know what is happening, all of our fishes are always dieing. I would like a fish expert answer. What is happening to these blue fishes? On their skin there are multiple grey spots, and another fishes are getti
Check the water chemistry. The discoloration could be due to elevated ammonia levels which can cause "burns". Use 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. The Neons (blue fish) appear to be infected with Ich, a parasite. Treatment is possible with commercial products found in the local Petco. Follow label directions carefully. You will need to treat the entire tank until all traces are gone. Removing a lump from your fish on your own is never recommended. You can cause severe injury. Most broad spectrum antibiotics (Kanaplex, Maracyn, Maracyn 2, etc.) found in the aquarium section of the local Petco should help treat or prevent infection. Choose one and follow label d

My goldfish has popeye and I have been treating it with Kanaplex. I have given my fish 3 doses of kanaplex and I don’t see him getting any better. The container said to add only up to 3 doses. Can I add more doses of kanaplex to continue treating my
Thanks for reaching out about your goldfish. Kanaplex has an antibiotic called kanamycin and is not absorbed systemically even if ingested, and fresh water fish do not drink water. The best treatment for popeye are systemic antibiotics (injections) and a carbonic anhydrase added to the water. A veterinary visit is highly recommended to assist with a diagnostic/treatment plan. Good luck.
