Hi, new to site today and new to fish keeping 1 year ago. Tank is 60cm long and holds 99 litres; internal filter. Hard water & PH 7.6 / 7.8. Intended inhabitants will be: 8x guppies; 7x lemon tetras; 3x honey gouramis (1m/2f); 6x panda corys; 4 nerite snails and a handful of amano shrimp. The ThinkFish website calculator leads me to believe I have capacity to add more fish. Would like to add a "feature" fish rather than increase levels of current inhabitants further. What are your thoughts / suggestions. Many thanks
That's quite lot of stock. Thinkfish tends to overestimate the stock compared to many other sources. How high does nitrate go between water changes? If it's rising quite high (40ppm max) I would stop at the stock you have. If not, then it depends largely on what you had in mind as a centrepiece in terms of how compatible it would be with your other stock and what would suit your water. I would normally suggest a male or pair of dwarf cichlids such as rams or apistos, but they're not practical as you have hard water.
