aquariumcam Posted September 1, 2021 Share Posted September 1, 2021 (edited) could I keep 6-8 harlequin rasboras with 8-10 black phantom tetras and possibly 6-8 neon tetras (and a mystery snail) all together in a 20 gallon long tank? I'm assuming that I maybe could but I don't want to be overstocking my fish tank. I want all my fish to be healthy and have enough space. Any help/advice is appreciated! Thanks.

Guppysnail Posted September 1, 2021 Share Posted September 1, 2021 (edited) Start with one species monitor your parameters if it permits add another etc. determine how much maintenance you are able to do knowing you may need to do more if you add more fish. You will also be able to determine if they have enough elbow room/swim room that way. If you add that many at one time though you will most likely experience problems as your bacteria Will multiply slower than the bio load added all at once. Mystery snails eat a lot and need fed a lot and produce A LOT of waste just so you know. 😁 Edited September 1, 2021 by Guppysnail 2 1 Link to comment Share on other sites More sharing options...
Intuos Posted September 1, 2021 Share Posted September 1, 2021 It's possible it just depends on what filter you have, how planted the tank is and how well seasoned the tank is. If you introduce the fish gradually over time it should be OK, you may find that you have to do a lot of water changes though. 1 1 Link to comment Share on other sites More sharing options...
Patrick_G Posted September 1, 2021 Share Posted September 1, 2021 The advice above is great. Here’s something else to think about. If you want to fit more fish in a small tank you can go for smaller fish. Like Maybe Green Neon Tetras, Chili Rasboras and Pygmy Corydoras. 2 Link to comment Share on other sites More sharing options...

I have a fluval 30 hang on back filter, an aqueon 100 watt heater, and I have driftwood with live java moss on it and 1 Anubias nana (planning to get more plants in the future), we already have the snail (got him yesterday). would you recommend more plants than that?

Intuos Posted September 1, 2021 Share Posted September 1, 2021 Definitely if you can afford it. Would also suggest that you look at watching the videos on turbo charging your filter on KGtropcals and aquariumcoop YouTube channels. 1 Link to comment Share on other sites More sharing options...

Fast growing stem plants and floaters give you the most bang for the buck as far as helping water quality. Snails love fresh blanched veggies 😜 1 Link to comment Share on other sites More sharing options...
