Proposed Stock

[jimlester]

Tank is 65l and current set up is 4 neon tetra's, pair of dwarf gourami's and two julii corys (all fish are fine and have been in the tank for approx 6 weeks). I recently added 3 cherry shrimps but they all died within 48 hours and am unsure as to why? Only chemicals used are Seachem for water changes and PH Minus.

Water is:

PH 7.4 (fluctuates to 7.6) have used PH Minus as read shrimps prefer softer PH
Amm 0.25 (Have now got all live plants to try to clear ammonia but can't seem to reduce it to 0)
Nitrite 0
Nitrate 10

Am wanting to add one more cory and 4 glow light tetra's but not sure if this will over stock the tank?

The shrimp may have died due to the ammonia level, not sure though.

Shrimp are very sensitive to water quality,and with a reading of 0.25ppm ammonia then this may have been the cause.

Its also not advisable to use ph minus,its better to have a steady ph than a ph that fluctuates up & down,this is turn will stress the fish.

I best way to remove the ammonia is though waterchanges.

As Harlequins says if your filter isn`t removing all the toxins then water changes is the way to go

Ideally you want your filter to remove 100% of the toxins leaving you to just remove the resultant nitrate with a good gravel vac/water change regime

The most common causes of high toxicity are over stocking, over feeding, decaying plants and poor gravel /filter cleaning technique

For your stocking, a 65 litre tank holds roughly 12-15 small fish (0-1.5 inches), count the larger gouramis as two small fish each, plus the rest of your smaller fish, I believe adding another four tetras would be fine, yet adding another cory would be too much. Corys are often better off in pairs anyway as they are not shoaling fish, and should a mating pair be in the tank then the other cory could end up a bit of a loner, causing him stress and discomfort.
