Thanks for reaching out about your aquarium. Sorry not very good at botany but there should be tropical fish clubs that might help in identification. But comments about your tank. First, not sure if light penetration will be good for a plant that low in the water column. Secondly, the balanced rock formation looks tenuous, and might fall. Good luck.

Check the water chemistry first. Use a home test kit or submit a water sample for testing. The local pet store or fish store may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with a nitrate level of 20 ppm or less. Perform partial water changes as needed to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. These fish produce a larger than average bio-load (wastes), so strong filtration is a necessity. The filter should be rated for at least twice the volume of the tank. The size of the tank may also be an issue. When keeping koi, tanks or ponds in the hundreds (or even thousands) of gallons are common. The number of fish in the current tank is too high. Consider getting multiple tanks or a significantly larger tank. 9 goldfish would need at least a 100 gallon tank. The additional koi increases this number.

There are several causes that can provoke these signs fro water imbalances to specific diseases like swim bladder ones. This problem requires a quite radical but logic approach. 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 fish should get 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.

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. Hope this answer was helpful, but 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.
