Question 1

Is it self cleaning???

Accepted Answer

Hi Shay, thanks for your question, it made me smile!  There are no self-cleaning aquariums. Filters reduce your maintenance.  Without a filter, you would do a partial water change every 1-2 days with a gravel vacuuming. With filtration in place, you typically do a good vacuuming and 30% water change every 30 days for a tank this size, but that is dependent on the types of inhabitants, and the quantity of them.  Replace filter media monthly, and take the filter system apart every couple of months.  Once your tank has been up for a month or so, begin adding Tetra EasyBalance Plus weekly to help reduce the frequency of water changes, and maintain water quality in between them.

Question 2

How many fish could you put in the 20 gallon tetra tank? We'd like to keep guppies, a cory cat or 2 and maybe some shrimp?

Accepted Answer

Considering the species you wish to keep, we would recommend one male guppy to two or three females (keep in mind they breed like rabbits) or a group of 5 to  8 male guppies, and at least 3 or 4 corydoras catfish of the same variety.  Total number of fish should be 10-12.  As to shrimp, that will depend a little on what type but typically for this size tank, about 4 to 6 should be fine.  Add these first so they can grow to a mature size and not be eaten by the fish.  Provide plenty of plant coverage as well.

Question 3

Anyone else have a problem with the filter? Its not working properly, doesnt intake water and just gurgles. Also lid on it doesnt fit.

Accepted Answer

Make sure your tank is filled to the top with water. Also, since the lid is not fitting correctly, the intake tube may not be installed right. Make sure it is all the way down into the filter box.  Last, but not least, fill the filter with water till it pours out of the spillway.

Question 4

what website can I get the cheapest tank from?

Accepted Answer

Petco and Petsmart often have tanks on sale. Petco has 50% off 'bare' glass tanks right now (July 2021).

Kits usually come with a poor filter and an LED light hood with barely any LED's in it, so people usually end up replacing both within a few weeks, so check on the descriptions, pictures, and reviews. 
If the tank is over 10 gallons, you are better off buying it in a store than taking a chance on having some careless gorilla deliver it, since glass tanks can easily leak if tweaked at all while being moved.
