Hello everyone, I have a 30 gallon (112 L) aquarium. It's been running for about 3 months and is fully cycled. I tested the water today: Ammonia: o ppm Nitrite: 0 ppm Nitrate: 5 ppm pH: 8.2 The parameters have been steady for about 2 months. I've had some issues with columnaris that I'm still dealing with in my 14 gallon (54 L) aquarium. The 30 gallon aquarium is planted and has 4 pieces of driftwood. In the tank I keep: 6 Guppies (1 male, 5 females) 3 BN Plecos 4 Amano shrimps 5 RCS The three Plecos look to be one male, one female and one who's too small to be gendered. The smallest one is about 1.5 inches (4 cm), the male is 2 inches (5 cm) and the female is 2.3 inches (6 cm). I've watched them a lot and they seem to be okay living together. They've found each their spot where they hang out most of the time. I know the Guppies will produce a lot of fry and I have options to rehome them when they inevitably will come. Am I over stocked? Thanks in advance for any help/comments!
