Patrick M. Bodega Aquatics Posted September 20, 2020 Share Posted September 20, 2020 Hi everyone! What is the largest fish that would live happily in a 35 gallon aquarium. I really do not want to cram any fish but I am looking for something large. Some of my ideas are below. Thanks! Link to comment Share on other sites More sharing options...
Sykes Posted September 20, 2020 Share Posted September 20, 2020 What are the dimensions? Long tanks lend themselves to different types of fish than highs. From your pictures, the oscar is almost certainly too big. Discus you *might* could do 1 in a 35, but I'd really rather see them in at least a 55, if not a 75+ (and in a school). The fish in your first image I'm not as familiar with. I'm guessing some sort of african cichlid? I know there's a wide variety there, but some can get quite big. I'd recommend looking for something that maxes out at about 6 inches or less. IMO, a school of small fish can also work really well as a centerpiece in place of a large fish.

Taylor Blake Posted September 20, 2020 Share Posted September 20, 2020 I don't really like the measurement of gallons to decide stocking. Tank size and shape matters much more in my opinion. I would recommend the a fish should have a minimum of 2x the Length of the fish for the width of the tank and 4x the length of the fish for the length of the tank. So a 6 inch cichlid should be in a minimum of a 1 foot wide by 2 foot long That is about a 20 long. So if the 35 gallon is 12 inches wide I would not do a fish that gets over 6 inches. If anyone disagrees with my thinking please let me know. Link to comment Share on other sites More sharing options...
FishObsessed Posted September 20, 2020 Share Posted September 20, 2020 (edited) Angelfish for sure. Perhaps a bloodred parrot cichlid. A peacock cichlid or 2 might work well. Firemouth cichlid. Discus, one alone might work but again,might be a stretch. Definitely not an oscar unless you want to move it when it gets bigger. Also fantail/fancy goldfish would be an option. These are all things (minus the discus and the oscar) that I would consider, with appropriate water parameters, in my own 38 gallon tank Edited September 20, 2020 by FishObsessed Link to comment Share on other sites More sharing options...
