Why Is My Betta Laying on the Bottom?
A triage guide to Betta splendens lying on the substrate: from harmless resting on a broad leaf to ammonia poisoning, swim-bladder disorder, and terminal decline in fancy strains.
Why Does My Betta Have Clamped Fins?
Clamped fins in Betta splendens are the earliest stress signal before any other symptom appears. Causes range from ammonia poisoning and low temperature to velvet, ich, and fin rot.
Betta vs Dwarf Gourami for Small Tanks
Betta splendens suits a 20–40 litre tank kept alone; Trichogaster lalius needs 60 litres for a stable pair and carries a documented iridovirus risk in commercial stock. This comparison covers tank size, temperament, parameters, disease risk, and tankmates.
Why Is My Gourami Flaring?
Gourami opercular flaring is normal anabantoid display behaviour in the right context. This guide separates brief courtship and territorial flaring from chronic stress-driven displays that cause injury and death.
