   ●  Good Fish for Warm Water Aquariums

The page, that you are now reading, is intended to help you choose a Compatible Group of Fish species first, then recommend the appropriate home for that Group of Fish.

 

Group 1
Neon Tetras, Glowlight Tetras, Harlequin Rasboras, White Clouds, Fancy Guppies, Corydoras Catfish, Glass Fish, Honey Gouramis, and Ghost Shrimp.
These fish are compatible and a few of them will do well in a 15-gallon aquarium with warm water. These fish are not compatible with most other species of fish. Click here for more about warm water aquariums.

 

Group 2
Danios, Swordtails, Mollies, and Platies, plus Bigger Tetras such as Black Skirt Tetras, Painted Tetras, Serpae Tetras, Red Eye Tetras, Black Neon Tetras, and Silver Tip Tetras. A few of these fish will do well in a 15-gallon aquarium with warm water. Each fish species in this group lives best in a group with several member of that species. Click here for more about warm water aquariums.

 

Group 3
Barbs, Gouramis, Sharks, Eels, and Loaches. Tiger Barbs and Tinfoil Barbs, plus Blue, Gold, and Opaline Gouramis, plus Bala Sharks, Red Tail Sharks, Rainbow Sharks, and White Tip Sharks. These fish are mildly aggressive and compatible with each other. They will grow fast and need at least a 29-gallon aquarium with warm water. Eventually they will need a much bigger aquarium. Click here for more about warm water aquariums.

 

Group 4
New World Cichlids. Firemouth, Convict, Pink Convict, Texas Cichlid, Jack Dempsey and other New World Cichlids are very aggressive fish. But many aquarists enjoy watching them dig, defend their territories, and care for baby fish. Large Plecostomus Catfish, Synodontis Catfish, and White Tip Sharks are usually compatible with New World Cichlids. 
Within a year or so a group of these fish will need an aquarium with at least 50-gallons of warm water. Eventually these fish will need an even bigger aquarium.
 
Before you get these fish, be sure that you are committed to giving them the size aquarium that they will need. Click here for more about warm water aquariums.

 

Group 5
Oscars and Large Fish. Red Oscars, Black Oscars, Tiger Oscars, and Pink Oscars will grow fast to very large sizes. Oscars are compatible with Bigger Pacus, White Tip Sharks and Medium and Large Plecostomus.
These fish will grow fast and soon need a 50-gallon aquarium with warm water. Eventually these fish will need an even bigger aquarium.

Before you get these fish, be sure that you are committed to giving them the size aquarium that they will need. Click here for information about warm water aquariums.

 
Group 6
Mbuna Cichlids. Auratus, Kenyi, Red Zebra, Pindani, Johanni, etc. Mbunas are from Lake Malawi in East Africa where they live among the piles of large rocks along the shore.

Mbunas are very aggressive and need to be kept in a group with at least 12 other Mbunas. If kept in a smaller group, the strongest fish will make life miserable for the weaker fish.

A group of 12 adult Mbunas will need a warm water aquarium with at least 50 gallons. Synodontis Catfish are compatible with Mbuna Cichlids.

Eventually a group of Mbunas will need an aquarium with at least 80 gallons of water. Click here to read a story about an 80-gallon aquarium with Mbunas. Click here for more about warm water aquariums.

 

Group 7
Peacocks and Haps. Malawi Peacocks, Electric Blue Haps, Yellow Peacocks, Jacobfreibergi and other fish that live away from the piles of rocks in Lake Malawi, where the more aggressive Mbuna Cichlids live. Keep a group of at least 12 of fish so the strongest fish not make the weakest fish miserable.

These fish will grow fast and need a warm water aquarium with at least 50 gallons. Eventually they will need an aquarium with at least 80 gallons of water.

Synodontis Catfish are usually compatible with Peacocks and Haps., but the Mbuna Cichlids, listed above, are not. Click here to read more about Peacocks and Haps. Click here for more about warm water aquariums.

 
Group 8
Angels. Freshwater Angels, plus Dwarf Gouramis and Neon Blue Gouramis, plus Neon Blue Rainbows make a nice compatible group of fish. These fish require a warm water aquarium.

Eventually they'll need an aquarium with at least 29 gallons of water, and an aquarium at least 18 inches tall is recommended for Angels.

Click here to see my 30-gallon aquarium that measures 24" high, and would be just right for this group of fish.

A Plecostomus Catfish is also compatible with these fish. Click here for more about warm water aquariums.

 

Group 9
Critters. Tadpoles, Fiddler Crabs, Mystery Snails, Crayfish and Ghost Shrimp. These animals do well in either a cool water aquarium or a warm water aquarium.

These critters are compatible with many smaller less aggressive fish, except the Crayfish, which are larger, more aggressive, and may bother small fish, but Crayfish are usually compatible with aggressive fish.

Puffer Fish love to eat Crabs, Shrimps, and Crayfish, so they are not compatible with these Critters. Click here for Information about Puffer Fish.

 

Group 10
Fantails, Telescopes, and Oranda Goldfish. Fantails, Black Moors, Red and Calico Telescopes, Red Orandas, Red and White Orandas, Calico Orandas, and Red Cap Orandas need a cool water aquarium or a pond.

You could keep a few of these goldfish an aquarium, but given good care and feeding, they'll grow fast and soon need a large aquarium with at least 10 gallons per goldfish.

The Koi and Pond Comets listed in the next group below are too aggressive for the Fancy Goldfish fish in this group.

 

Group 11
Pond Comets and Koi. Fancy Koi, Red Pond Comets, White Pond Comets, Red and White Pond Comets, and Shubunkins are pond fish. They are usually not compatible with the Fancy Goldfish listed in Group 10. Click here for more about ponds and pond fish.

 
 

The Groups of fish listed above are just some suggestions from the many good combinations of fish that you could keep.

 
 

What Won't Work.
For many years many aquarists have been advised to pick compatible tropical fish fish from certain groups. These groups had names like co
mmunity fish, aggressive fish, semi-aggressive fish, etc. There were some very elaborate systems, but these methods all repeatedly caused problems for aquarists trying to pick compatible fish.

What Usually Works.
Sometimes you've decided on a fish you'd like to keep, or you already have a couple of compatible fish, and you'd like to get another type of fish. The best method is to look at our Indexes, find the fish that you already have on those lists, click on the link to more information about that fish, then look at the paragraph labeled "Compatibility." Usually you'll find five or six types of fish listed that will be compatible with the fish that you already have.

 About our Fish ...
Almost all the photographs and videos, shown on this web site, were taken by us of our fish in our aquariums.
 
Compare the healthy, beautiful, energetic fish in our beautiful aquariums to the fish in our competitors pictures. Their fish often look thin with clamped fins and poor color.
We buy the highest quality fish, produced by the best fish farms or caught by the best collectors of wild fish, then we take incredibly good care of our fish in our beautiful aquariums.
 
If you compare the pictures on this site to our competitors pictures, you can instantly see, our fish and aquariums are better!  ;^ }
Will the fish you get from us look like the fish in our pictures? No! This is similar to buying kittens and puppies that will change as they grow to become cats and dogs.
 
We stock and ship fish that are the ideal size to sell. Not so small that they will not do well when shipped. Yet not so big that they have become much more expensive.
 
The fish in almost all of our pictures were young fish like the ones we have for sale that we raised up, and you can too!
