Tribble Breeding can be a fun and interesting part of Star Trek Online gameplay. There are as many as 40 different sub-species of Tribbles: some of them provide a quick heal and are pretty common to find, while others are more rare and give various types of buffs to the player (or any Bridge Officer who has them equipped) when used.
In order to breed, Tribbles must be fed; in other words, food or drink must be placed in the same area as them. Tribbles can be bred in the player inventory, while equipped in the player's device slots, or in your personal bank. Tribbles do not breed in Bridge Officer device slots, the Account bank, and the fleet bank.
- Tribbles breed every hour, on the hour, after you've started playing the game.
- Your game time can be found by typing in /played in the chat window.
There are three levels of food and drink: +56%, +64%, and +72% food. The higher the HP boost a food/drink provides to the player, the more rare it is in-game, and the more it is needed for higher-level breeding.
To breed higher level Tribbles (Tier 4+), lower level Tribbles must be fed specific food items. For details on which food items are required to breed a Tribble, click on that Tribble below or check the Tribble Breeding Table.
It is possible to intentionally bulk breed multiple tribbles at the same time. Just ensure that the number of food items equals the number of parent, or stud, tribbles, and that the food is not stacked. One food item per cell, per tribble. However, there is no safe way to ensure a specific offspring if different stud types are in the same zone, as there is no way to control which food item any given tribble will eat.
Alphabetical List of Breeding Food
Any food not listed below will produce a tribble, low level, unknown type.
There are eight levels of Tribbles in the game — nine if you include the Best Buy pre-order Tribble with all 3 possible buffs at once. While all non-preorder Tribbles can have two buffs, one buff, or no buffs (simple heal), some provide more powerful buffs than others.
A Tribble can only breed other Tribbles at the same or next level as itself with the right food. With the wrong food, a Tier 1 Tribble will result. Below is a list of the levels of Tribble sub-species players will encounter.
For example, if a Tier 6 or 7 Tribble consumed a food item that gives a boost below +72%, a Tier 1 Tribble will replace that food item. Hence, breeding should be done in steps, with all Tier 1 Tribbles being removed before breeding Tier 2 to Tier 3, and so forth.

Tiers 1 to 3
Tier 1 Tribbles only can be found in enemy loot (Klingons, allies and enemy crates) and only provide a simple self-heal. Tribble 1 or 2 tribbles result from feeding any tribble any level of food below 63%.

Cannibal Tribbles are not part of the normal breeding tiers, but operate in a similar manner. Tribble foods can be made through Klingon duty officer assignments. When fed to tribbles, it produces a cannibal tribble which will eat other tribbles in your inventory. These can then be turned in at Klingon security officers as part of a Tribble Bounty. Cannibal Tribbles can also be acquired occasionally via a critical outcome of the duty officer assignment Assignment: Confiscate Contraband From Crew.

Special tribbles are either bred by feeding any tribble a particular food (i.e. the Gamma Quadrant Tribble can be bred by feeding any tribble ketracel white), or they are otherwise purchased and unable to be bred (i.e. Tribble of Borg was originally a testing reward and is now obtainable from the c-store). Feeding these tribbles regular foods usually grants a tier 5 tribble.
