More importantly, see to it that the fish you will be bringing in is not at a stage of growth that can make it easy prey for the goldfish. That entails knowing the fish that you are planning to introduce in detail and also ensuring that all is set to welcome it into the home. To wrap this up I will like to state here that you should not hit the store to purchase any one of these fishes as tank mates for your goldfish without doing what is needful. Diet: lettuce, flakes, spinach, cucumber.Just like the goldfish, the rummy-nose tetras also cherish a habitat that is filled with some greenery. They delight in moving about in the middle of the tank but are never scared of dashing to the top and bottom in some instances. Rummy-nose tetras will add beauty to your tank as they are colorful and love to keep their shoaling party. You should, however, bear in mind that a little extra will be needed from you to take care of them as they do so much to tolerate unfavorable water conditions – they are pretty sensitive to such sudden/unusual changes. The rummy-nose tetra is yet another friendly fish that can make a peaceful abode with your goldfish.

With all these, the Rubberlip pleco should not compete with the goldfish for food and space. They are yet another ravenous eater of algae. They are nocturnal species that are well-inclined to staying at the bottom of the tank where they display their scavenging characteristic. In the wild, Rubberlip plecos dwell in moderately flowing water with rocky undersurface, and they have a high demand for oxygen. Though not a very regular or common choice of a tankmate for the goldfish, the Rubberlip pleco will, without an iota of doubt, make a peaceful community tank. Diet: Brine shrimp, bloodworms, tubifex, daphnia, mosquito larvae, fruit fly, flakes, freeze-dried foods, vegetables.They cherish a densely vegetated habitat and will need some hiding spots on certain occasions. Swordtail fish are active swimmers, moving around the top and middle regions of the tank. However, while they can survive in varying water conditions, they are not so tolerant of sharp/sudden fluctuations in temperature. They are quite versatile in that they can thrive in both freshwater and saltwater environments. Swordtail fish are the schooling type but will have no issues sharing a tank with others from their ‘clan’.

These amazing species are very peaceful and sociable. The swordtail fish has the right size and temperament to make a compatible companion for a goldfish. Diet: Sinking wafers, vegetables, plant matter, brine shrimp, freeze-dried foods.
