S.O.S. Monodactylus. Hi guys. 2 months ago I bought 6 small monos in my discus tank. Yes I know. Discus are a pacific guy and mono are speedy guys. Respect between them, normally... But I tried ... They eat good but somedays one of them runs erratic movements like drunk and in 24 hours died. 3 weeks after another one of them too. And another... What is the problem? Ph 6,7 and temp 28C. The aspect of 3 others is very good and eating very fine, like discus. Please, some ideas?... Thanks! Ciclopexx@hotmail.com

    That's a bad mix. Discus need a PH of 6.4-6.8 and soft water. I use 1 tablespoon of salt per 5 gals of water. The Mono fish need a PH of 7.8-8.2 and hard water. 1 tablespoon of salt per 5 gals of water is a good start for Mono fish but it will need to be much higher as they grow.

I have 4 awesome Mono fish in my 3 ft by 1.5 ft by 1 ft tank. From last 4 months and they have grown nicely. It's a great feeling to have to keep them. Please tell me more about them to make them more healthy and happy.

    Add around 1 Kg rock salt to your aquarium. They need brackish water when they get older.

    Almost you can keep them in 2 and half feet by 15 inch by 15 inch tank.

    I'd say at least a 55g if not bigger for 5 of them. They get about 10' and need room to swim and grow. I have 1 in a 90g.

    You are going to need a bigger tank for these guys. They are suppose to be in at least a 55g if not bigger for 6 of them. They can grow up to 10' and live up to 11 years.

I just got a silver mono and it was in a brackish tank at the fish store. I was a little worried that he might die cause I have a fresh water tank. But he seems to be doing just fine and I am very happy with him. He loves the rocks in my tank and is very active. Great fish to add if you have at least a 55g tank they need room to swim and grow.

    Try and add more places for retreat.  Areas that will break the line of sight sometimes work.

    I would get more of them..if you have the room in your tank. So its not just one getting picked on all the time.

I just bought a single mono and have kept it with 2 gold fish, 2 sharks, 1 ghost & few guppies! Although read that they are not fresh water fish. But they were kept in fresh water from where I bought them. Is it really a bad idea?

    Mono Fish usually do fine as youngsters in freshwater aquariums. But as they get older they usually do better in a brackish water environment.

    These are difficult fish to keep and they are schooling fish and should be kept in numbers.  10 gallons is too small for them.  Is your tank a freshwater set up?  Very important to find out what environment that they came from.  If the petshop had them in brackish you will need to know the salinity so you arent shocking them.

I have 4 mono's and 3 columbian sharks in my 110 gal tank. We have had two monos for over a year and added two more a week ago. I've noticed one of my new monos have been getting picked on and he looks depressed, swimming at the top away from the others. How can I get them to all get along? Please help! I love all my fish but it's very sad to see this!
