Aquarium Advice Apprentice
I have a 25g tank I kept 7 orange von rio tetras, and a single angelfish, all but 3 von rio’s (transferred to a different tank) made it within a week. I got the tank from my neighbor and cleaned it about 4 times thoroughly with a vinegar and water mix, then rinsed and cleaned with water like I have done with all my other tanks and none of them have ever had this problem. I had a big decoration in the middle I also cleaned well, but my friend thinks that might be the cause of it? The decoration was also gotten from the same neighbor.
But I don’t want this huge tank to go waste, especially after all the money I put in for it, but I don’t know if I should put other fish in there (obviously after draining, recleaning, and recycling the tank) for fear the same thing might happen again.
Moreso should I get a new substrate? I currently have activflora bioactive granulated gravel in there as well as some standard black gravel to make 26 pounds, rinsing this gravel isn’t very recommended since it can kill some of the beneficial bacteria but I don’t want it to be possibly ‘infected’ with whatever killed the other fish, are my only options to rinse it or throw it away if this tank is even able to be used again?
