I have a low tech heavily planted Fluval Spec V. Current stock are 5 male tiger endlers and around 30 cherry shrimp (currently, they are breeding). The endlers seem a bit shy and spend much of their time hidden in the plants, so was considering adding a few more. AqAdvisor tells me I shouldn’t have endlers in this tank at all and I get conflicting advice from this forum about whether the spec is suitable for fish at all, so thought I’d ask for your opinion again . Also considering adding some Pygmy corys! Doing massive water changes on this tank is not an issue. I do 10- 20% 2-3 times a week as it takes 5 minutes. Stock all happy and healthy and plants need regular pruning so I assume all is well, but I don’t use test kits so no idea what water parameters actually are.
