Lyon Aquascapes Posted October 17, 2021 Share Posted October 17, 2021 (edited) Hello Coop community, First the tank details and info then below is my fishie issue: South American Style heavily planted aquascape. 300 liters / 79 gallons Filter: Oase 600 biomaster and eheim skimmer unit Water parameters according to Coop test strips: Nitrate: 0, Nitrite: 0, Hardness: 0, Buffer: 0, PH: 6,4, Chlorine: 0, Temp: 23 C / 73,4 F CO2 injected at about 20 / 30 mg per liter via inline system (comes on 2 hours before lights and goes off 1 hour bf they go off). 10 hours of lighting per day. Fertilizer: Dennerle fertilizer system. Inhabitants 9 angels (Bulgarian Green Seal Point), 20 cardinals, 20 green neons, 16 corys (orange lazer and eversi), 7 panda garra, 1 whiptail cat, 2 flying foxes. The water we have is really soft (Black Forrest, Germany) and it isnt RO its just mountain water. But almost all my species are south American originally or from areas that have soft water. I used to do 1 50-80% water change every 2 weeks but now I do it every week since the start of the month bc of my current issue (see below). Feeding 1-2 a day. 1 day of fasting / week. Now here is my problem: My angels are having some issues with their dorsal and anal fins (top and bottom ones). In the photos you will see they are slowly deteriorating on the top and have some slime on them. They are also attracting what seem to be the co2 bubbles. There seems to be some stringy substance coming from the fins. To try to improve the problem I have upped my water changes to once a week and also added lots of catappa leaves to see if that would help. I am thinking of using a catappa concentrate (https://www.sera.de/en/product/freshwater-aquarium/sera-phyto-med-catappa/) starting tomorrow after a water change to see what that does. My fish are eating well, super active and the colors are very good atm. So I am really at a loss for what is going on. It is also only the angels that are currently having this fin problem. Other fish seem to be just great. Any thoughts or ideas would really be helpful. I want to get their fins healed up and be a good fish papa! Many thanks.
