65 gallon rebuild

I added some fish this weekend, a trio of Iriatherina filamentosa and a good sized solitary Corydora aeneus that was with some Corydoras paleatus in the lfs, lousy leakage in the tank where she was, a lot of brown algae and very poor oxygenation. So, new pictures and you can see someone who is back in the tank ?.

I had planned to uninstall this tank this weekend, but I'm barely recovering from a bad cold that I still have, I even thought about the virus but it was not like that, I received my first dose of vaccine just 11 days ago, right on my birthday What luck, I guess.
I'm having problems placing the fish with other aquarists, they are not cheap and most of them are not interested in the species I chose for this tank, they are looking for cheap goldfish or fish that are easy to care for like a platy, so it will be complicated, also all the plants are gone, most died and I sold the plants that were left alive as anubias and cryptos, I was happy with the tank most of the time, and it will probably be my last freshwater tank, or at least my last in a long time.
 
Hello fishorama, thank you, I'm better now but I will wait to make any moves with the tank, I have plans to "trim" it and turn it into a 30 or 40 gallon salt water refugium, I will buy equipment and I will improve my system, so the freshwater will be gone, maybe it will come back or maybe not, I don't know, but it has been fun without a doubt :)
 
Well, this project has remained in the past, I have kept some fish, I was only able to sell the cardinals and I was able to take advantage of to dismantle everything, my colisas couple disappeared from the tank, I did not even find their corpses, also the albino angel died suddenly, it was sad to see it die since it was the freshwater fish that I have kept the longest, I see it unlikely that the fish that I still have will be sold soon, I have only decided to keep my plecos and my Kubotai loach, so I will place them later in a cheap tank you can get. I have plans to trim the tank and use it as a 40 gallon refugium for salt water, but if the cost of this maneuver is similar to a new tank with that litrage then I will choose to sell the tank and make the shelter in a new tank. .
