That Fish Blog – Aquarium Advice and Information

Hey out there! This time around I’d like to talk about setting up a tank for Mbuna, or “rock dwellers”. You can find these colorful fish in the any of the three rift lakes of Africa, but for this blog we will talk about the preferences of species from Lake Malawi.

First, the tank. Larger is better for a couple reasons. A 55 gallon is nice, but a 75 is better for these fish, with its 18 inch width. narrow tanks can be a pain since you’ll want a lot of rock for these fish. The second reason would be that the more room you give them the easier it will be to control aggression. I was once told that if you crowd these fish, they wouldn’t be as aggressive, not being able to single out others to target and bully.  I have seen Mbuna tanks with 12 to 20 fish dwindle down to 4 to 5 fish due to dominant fish. I think it depends on the species and particular fish that you’re trying to house together more, and I don’t think crowding is ever good advice. Last but not least, the larger the tank the more choices you have when it comes time to choose livestock. Read More »

The Marine Bio staff That Fish Place gets a lot of questions about husbandry of fish and inverts in aquariums. When adding any new inhabitant to an aquarium we recommend researching the conditions, max size, and temperament of the species you are interested in to ensure that it will be a good fit for your tank and the other creatures you may already be keeping. And, as always, quarantining new additions in a separate aquarium is highly recommended.  If in doubt, we’re always here to answer any questions you may have so you and your aquarium continue to stay happy!

 One question recently submitted was from Al in New York:

 I’m going to be starting up my 55 gallon set-up with blue rams. My questions are what will make good tank mates? What water conditioners might I need? Should I use live plants, and if so which do you recommend? How many rams should I add?

 Marine Bio Responded:

There are several fish you can keep with rams. Lemon tetras in a school of 6-10 would be nice. Serpae tetras in a large school of 8 to 10, or Brilliant rasboras in a similar school would also work well. These are fish (introduced gradually) that I would start with once the tank is established. Rams should not be added to the tank for at least 2 to 3 months after the introduction of your first fish. So you can maybe start with 6 Serpaes or Brilliant rasboras, and let the tank run for with nothing else added until the cycle is complete.

During this time, you can certainly add plants if you wish, but do not add more fish. I am a proponent of live plants in aquariums. They make for a beautiful and healthy environment, and many fish will do very well in a planted tank that is similar to their native waters. Plants that you can add may include Rotala, Ruffled swords, Ozelot swords, dwarf sagittaria, and Bacopa. These are all nice plants to start with, and there are others you may prefer, it is all according to taste and the lighting and conditions you present. Just make sure you add Flourish Iron or a similar product to your tank to help your plants to stay healthy.  

After you cycle your tank with the tetras or rasboras, you can add some Corydoras Catfish in school of 5 or 6 to help keep the bottom clean. Some smaller pleco species may also be considered.  Rubbernose plecos, for example, are great algae eaters in planted aquariums, as are Bristlnose and Medusa plecos. Gold nugget plecos and Queen Arabesque plecos would also work, and they are really attractive. When you are ready to add rams, I would think a small group of 5 or 6 would work out great for you, maybe 1-2 males and the rest females.

Water conditions? Well, rams prefer warm, soft water. So you want your temperature to be in the range of 80 to 82 degrees, and your pH should be around 6.5 to 6.8. You may need a buffer to maintain the keep the water at this pH and there are several available to choose from and keep on hand for water changes and maintenance including Seachem Discus Buffer.
