    Mono Fish will turn black when they are stressed, and that is a sign that something is not right in their environment. However they may turn black at night too, which is normal.

    Tonight I add few drops of seachem stability. And both of my mono fishes color has turned to black. Is that normal?

    Cloudy eyes are often a bacterial infection, but they can also be the result of Ich or Velvet. You can find information about eye problems and these other diseases as well as how to treat them on the Aquarium Fish Diseases and Treatments page.

I have three mono`s that are the size of a dinner plate. I have had them for 11 years, and they have lived in a freshwater tank since I got them at about 1 in. They also had three angel fish, and three silver dollars. all pretty big fish now. I just noticed that the monos are killing the other fish that they have lived with all these years. Does anyone know why? Are they getting to breeding size? Should I put them in a saltwater tank? They have been in a 125 tank. HELP""""""

    Doreen--Seems obvious but big fish=big appetite. Larger tank and no smaller fish with them or take them to a fish store that may give you some credit. Any fish that eats my fish is going away. Might consider fillets and invite friends over for a nice fish dinner. Good luck.

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.

I kept mono's in my fishroom before, but not for many years. Yesterday, I came across a deal in my local fish store that I could not pass up. I bought 12 small mono's for a very low price. They are about the size of a quarter dollar coin and all appear healthy and active. I'm now in the process of moving some other fish out of a 125 gallon aquarium and rearranging it to suit the mono's. I'll keep them in freshwater for now - my well water is very hard (12 dGH) with a pH of 7.8-8.0. I'm considering adding a large group of mollies for dither fish, and maybe some small synodontis cats for clean up. I'll probably plant part of the tank moderately heavy with vallisneria which will hold up well to the mono's nibbling and even to the addition of low salt levels later on. Today I fed the mono's some raw boiled zucchini and later some live brine shrimp - already they are VERY eager eaters and their schooling behaviors are delightful! I'm looking forward to watching these guys grow and thrive in their dedicated system and hopefully will enjoy several years of their presence and activity in my home.

I just got 4 mono fish and I was wondering if they came from a salt water tank, and I put them into a freshwater tank will they survive?

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!

    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.
