I have a few problems in my cichlids tank currently. 1. There are these tiny white gnat like flying bugs coming out of the water? 2. Brown algae on the glass won’t go away! But I have snails and an eel so I don’t know what to use that won’t kill the
Those could be copepods. They are typically harmless and difficult to completely eradicate. On the good side, they are a sign of a healthy tank and are useful in eating decaying matter in the aquarium. The brown algae can be due to insufficient lighting or lighting periods. You can wipe down the glass and plants, perform a partial water change and increase lighting. It can take weeks to month to resolve. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Confirm stable water chemistry and quality. Make sure the water temperature is correct as well. Too warm or too cold can cause stress. Look the Jack Dempsey over for signs of injury or infection. Ich, bacterial infection or fungal infection can cause the fish too twitch or shiver. Plain aquarium salt (NOT table salt or Epsom salt) dissolved at 1 tablespoon per 5 gallons of water is a great general tonic that can reduce stress, improve gill function, treat minor infection and aid in any recover

Check the water temperature. Low temps can affect appetite and digestion in fish. Angels do best between 78 F and 80 F. You can soak food in garlic juice to stimulate his appetite. Next, check the water chemistry. This can be done using a home test kit or by submitting a water sample for testing. Most pet stores will do this for free or for a small fee. Confirm 0 ppm ammonia and nitrites with nitrates at 40ppm or less in a tank with live plants or 20 ppm or less in an unplanted tank. Partial water changes can be done, if indicated, to stabilize chemistry and/or maintain water quality. use only aged or conditioned water that is temperature matched to prevent stress or shock. Although they do best in slightly acidic and soft water, they are quite adaptable. Fast him for 2-3 days then feed bits of cooked and shelled green peas. if he is constipated then this should him him get regular again. A broad spectrum parasite medication, such as PraziPro, should be considered. You can find it in t

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.

Hello, can you help me identify this plant please, the people at the store didn't know the species. Also is my aquarium good
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.
