r/TetraFish

I feel like you know the answer to my question but over the last 2 months I have leaned hard into getting Neon tetras and Cardinal tetras. I understand how neon tetras are very inbred now and subsequently a sensitive fish. I just did not think I would lose like 2 or more every 2 to 3 days. I added approximately 70 cause i got them cheap and i barely see 20 now, one month later.

I want to say my cardinals are better but not by much.

I am writing to see if this is really just the way things are for everyone else or if there is something that I just need to be doing nowadays.

7 Kuli loches

2 bamboo shrimp,

5 amanos

dozen blue neo shrimp

snails

I was trying to go for an amazon biotope type tank, focusing on a cloud of cardinal and or neons swimming back and forth. I went neon first cause i could get a huge amount super easy where I am and for cheap.

I appreciate any ideas.

I got 10 ember tetras a few months ago (maybe 4 or 5 months) and now i have 1 baby ember. Does anyone know on what scale ember tetras are in terms of producing babies? I am wondering if I should wait before introducing a different group of tetras or if the ember tetras will basically fill my tank's capacity within a year. I am still traumatised by guppies...

I was given 3 black skirt tetras last night by a family friend who knew I kept fish. Her son wasn’t taking care of them and she wanted them to get healthy and happy again. They are currently secluded in my hospital tank while I rehab them, but I’ve never owned black skirt tetras before so I’m not sure where to start with tank setup.

I have a couple different sizes of vacant tanks already that I would need to build, but I’ve got 4 already fully functioning and pretty self sustaining freshwater tanks that I can use to help quickly cycle a new tank. As far as plants and possible tank mates I’m not sure where to begin and I’d love some advice!
