Companions for your Guppies

By now, your guppies have settled into their tank and you have enjoyed getting to know and enjoy them. I imagine your confidence has soared and you have the urge to have some different inhabitants. This is where the term community tank takes its meaning. Not all fish make good companions for other fish. The guppies are a peaceful fish and get along with other livebearers like mollies and swordtails. These small fish are covered with the big name of Cyprinodonts because they have teeth.  These groups are named toothcarps and cover both the livebearers that have live fry and the fish that lay eggs. So if you hear different names for the same fish this is the reason.  Most community tanks will have the addition of catfish or suckermouth fish to help in algae control.



My favourite addition to a community tank is catfish, the very shy algae eaters that scoot from dark corner to an even darker hiding place. The catfish live primarily on the bottom of the tank but you will see them moving all-round the tank attached to the glass with the sucker mouths they possess, or moving in a flash through the water. While the catfish I have are pleco’s, they are just one of over 2000 species. The common plecostomus can live a long time, and you have to be aware that these fish can grow quite large.

They do like vegetable matter to form the greater proportion of their diet. They will eat sliced courgette or peas with gusto! Pseudo fights for ownership of peas dropped into the tank will happen between the guppies and catfish.  They will also clean up dropped food after the guppies.  There are also specific foods just for the pleco and they feel very special getting these treats. These fish have wonderful personalities if they qualify as having one! I have always had bogwood in the tanks; the pleco does like these and during the day will hide or spend time on or around the bogwood. The male has more whiskers that are prominent on his snout, where the female has a more reduced number just around her nose.

The breeding habits of the bristle nose pleco are interesting to see. If you have provided a cave or tube like structure for them to hide in or under, you may notice the male “sweeping” or tidying the house. The female appears to attach the eggs to the walls of what ever the adults have elected to use. The egg sacs are noticeable in that they are an orange color. This makes them very noticeable to the fry “eating” guppies. The parents seem to watch the small pleco’s but you will only know they are in your tank when you see the little fish amongst the pebbles and plants in the bottom of the tank. Guppies will eat anything they find so you will need good hiding places to rear any real number of the little pleco.  These are excellent fish to have in a community tank.
