Too Cramped and Overstocked?
I have a 6.6 gallon tank. It has been running for 14 months now. I have 6 male endler guppies and 5 Neocarodina shrimp, and some mesa ramshorn snails. Does this feel or look cramped or is it overstocked? Could you give some suggestion or recommendations anything helps. I am also planning on filling the middle empty space with water sprite.
My water parameters after a week:
Ammonia: 0
Nitrite: 0
Nitrate: 5
Ph: 7.4-7.6
Thanks in advance.
