Hello Folks, I'm still thinking of "Project Discus Tank", but I have a few questions and concerns that is holding me back... I do know about the cycling, beneficial bacteria, water changes, water parameters, etc, filters, tropical fish community.... but I have zero experiences in Discus keeping. Questions: 1. I'm thinking of getting a 125 Gallon tank for Discus school., Is 125 Gallon okay? I've heard that they require a big tank and I do not want to get a 55 Gallon tank (i think its to small). 2. Can I make it a planted tank or just driftwood? 3. How many Discus can fit in a 125 Gallon standard tank comfortably? I do not want to jam pack the aquarium just to have many fish...I want the fish to have space to swim... 4. I know that they require a mature tank....so after the cycling process is completed...how long should i wait to add my Discus fish? 6 months, 12months? 5. Can I keep Kuhli loaches (12 of them) with Discus? I am thinking of transferring the Kuhlis from my 56 gallon to the 125 Gallon only if they can co-habitate with Discus along with my cardinals? If not, I will probably give the 56 Gallon tank and all its residents to my sister or brother. I do want to two tanks at my place. thank you.
