I have a 20 gallon tall on a diy 2×4 stand with a glass lid and marineland penguin filter for sale for $40 or trade for 20 long (back of 20 tall is painted black). Bought it a few weeks ago and haven’t used it yet but I’ve decided to get a 20 long instead.
I also have a 29gal that the angelfish is in (along with a BN pleco who is not for sale) with a cycled sponge filter (if you buy the tank with the angelfish I will give it to you for free, you will probably need other filtration along with it as it’s rated for 10gal but I currently am using two of the same with stable parameters 0 ammonia 0 nitrites 10-20 nitrates) and 300w heater (it’s working but light occasionally flickers so I’m not going to add that into the price). No stand but has a polycarbonate diy lid. $50 with the angelfish or $30 without but angelfish will need to be sold prior to purchase. The angelfish is slightly aggressive. He has not bothered my pleco much, and was previously housed with corys and snails with no issues).
