They are way too big for their mouths it’s a shark that isn’t fully grown and parrot cichlids and angels who have notoriously small mouths. As for water chemistry idk what’s going on here. The tetras are the least concern man lol
as a professional at fish keeping (6-7 years of experience) this is WAYYYY overstocked, and has too much of a variety of sizes or fish, i suggest buying a 100-150 gallon, this isnt a reccomenation, you NEED. a bigger tank, and better substrate as you do have afew bottom dwelling fish, and include obstacles and REAL. (HAS TO BE REAL) PLANTS. i rate this tank a 1.9/5
The comments man everyone like the tank is too small no it isn't at all. Anyone who complains about tank size i know instantly you don't know what your talking about the only fish which will get large is the severum and a 55 is fine.
People here complaining about the tetras getting eaten by cichlids and angels lol. Their mouths are way too small their concern should be husbandry and water chemistry but they’re worried about tank size? What lol
Do some research,I have google no excuses,tank wrong in so many ways substrates terrible,if u do it right the tank looks after itself less maintenance and happy fish nice effort but do wrong
