Would my 20 gallon tank hold a Largemouth Bass ? I have been wanting to keep a Bass in my tank for years . I have once but the Bass didn't last a day , due to the fact he was eaten by my Flathead Catfish . Since then , I have released the catfish because he ate every fish in the tank and he was almost the same size of the tank . I currently own a 2 - 4 inch juvenile Rock Bass , which is on a diet of chopped chicken liver ( 2 - 3 pieces a day ) and he eats earthworms and occasionally pellets . I keep a variety of foods for all of my fish , I also name them to make it easier to remember who likes what . Anyway , could I keep a Largemouth Bass in my tank ? With a approximate size of 4 - 6 inches ? If so any tips or suggestions are appreciated .

Unless you have plans for a massive tank, no. And dont release fish into any waters after they have been kept in an aquarium. Enough issues from people doing that already
 
Post sounds trollish. A flat head in a 20?
I released the Catfish at the same lake I caught him at . He won't have that much trouble readjusting . The only fish I have a problem with people releasing to other lakes is Carp . The lake Desoto National Wildlife Refuge is ruined by Carp , sadly . If only Carp didn't exist ...
 
I don't know if this is a troll but if it's not I will tell you one thing bass get big. Not one pound big. If let be bass can reach up to 20 lbs and almost 3 foot long in some cases.(not saying its common but it happens)Bass have no place in any tank less than 500 gallons and that's still too small. Bass are cursing fish they don't like to sit still unless spawning and do most of their lives swimming from deep to shallow , much like a shark would even though they are nothing close to a shark just leaving an example. Being an avid catch and release bass angler I must tell you that when I come up on a bass and they see me they get spooked this may pose a problem in a fish tank. They also relate to cover and structure. This doesn't mean petco or petsmarts little rock hides or fake plants ,this means hydrilla sunken trees old roadbeds and mounds of rocks and logs. Certainly a 20 gallon would only serve just as a 5 gallon bucket would while waiting for your buddie to bring the scale over to weigh your catch. And that's not even the correct size. So please if this is a troll stop and if this isn't a troll consider what I've said. I haven't said it all but I'm not going to type for hours if this is a troll what I'm leaving on the bottom of this post is a picture of a bass caught in japan at Lake Biwa it's caught by manabu kurita on a large 12 inch Swimbait I believe this is just a reference of just how large bass can get if let be in the wild. I don't know what units were used to measure but the bass came close to 23 pounds or something I believe definitely wouldent fit in a 20 gallon or even a 50 gallon or more it just won't work man just stick with the little rock bass or even better get a 55 gallon and stick with the rock bass they can still get pretty big and depending on where you live what you are doing may be illegal

The issue with releasing fish are a few things. One, they arent likely to survive. 2. You could introduce a fish not native and 3. (Most importantly) you could introduce illness that the native area isnt used to.

Say your flathead picked up a resistant form of ich from aquariums and then brought that into the local lake. Kinda like how pilgrams nearly wiped out native americans with small pox. Risk vs reward is so far from worth it. I could go on for days on this subject and how its giving our hobby a bad name. Look how many states ban piranha and rays. All because some people cant be trusted and do stupid stuff now south florida has more SA species than natives
 
I don't plan on getting a 20 inch bass ........ My tank can hold 5 fish max ... Bass can get big , but it depends on how big their environment is ... Bass just don't grow non stop ... It all depends on how big their area is .. I plan on getting a baby bass ... Not an adult size Bass ...
