I don't even know what is happening :( woke up this morning to find sheldon dead :'( here's some info about his set up to see if anything stands out that could have been wrong.
Tank size: 40 litres
Filted?: Yes, with low flow
Heated?: Yes, temp at 79F
Declorinator?: Yes, use Prime
Food: Biogold Pelletes and tropical flakes and fed 1-2 a day but didn't eat much and sometimes very little.
Tank mates?: was with some neon tetras and rasboras for a day but moved them to my other tank.
Plants?: Had 4 live plants in, no plastic or silk.
Activity: Was active first two days I got him, third day, activity decreased.
Physical apperance: Looked fine, not underweight and no stress stripes, no signs of illness.
Issue: Don't know. Brought him home, ate 2-3 pelletes and didn't eat much to nothing since then. Removed tank mates straight away after about a day and still didn't barely eat, showed no signs of illness.
That's all. Upset that I can't keep a simple pet alive, his old tank mates are fine though. So got screamed at by my dad this morning and being accused of not looking after him :'(
