Stocking Question

[badboyace84]

hi guys i have a quick question on my fishtank stock i currently have 14 leopard endlers, 13 lampeyes and 2 koi swordtails today i also bought 5 green neon tetras and they are all looking very happy and healthy but was thinking about getting another 5 of the green neons those being my last fish for my tank but i was wondering weather this would be 5 fish too many?? my tank it an aquaone 620 that holds 90 litres
thank you in advance

the rule of thumb is every inch of the full grown is a gallon needed for every inch. you may already be overstocked.
