Yeah. I believe in understocking. Way less issues along the way.

Besides I could not maintain daily water changes on a tank that big. So low stock allows for weekly changes instead

Salt - never heard of that approach for Altums before

Ya my setup is the exact opposite Haha. I have 4 in a 48g with 8 rummynose, 12 Cory's and some plecos. And I don't do water changes just top ups. I heavily rely on aquarium salt but looking into a bigger tank in the future. I started using uv sterilizer I think it helped alot also my rummynose red noses are much brighter.

Rummynose are great - I have them on my list to add. Just concerned they might get eaten if too small. The biggest angel is about 10" tall and has a BIG mouth!

How old are your angels?

Rummynose are great, they let you know how the living conditions are in the tank.

I have had them for 7+ months.

Just a few update pics. Largest specimen is close to 10" tall. Smaller individuals are 7"-8" tall

Tank update:

Took a vacation over summer, had a friend come in and look after the tank. Feeding went well but water conditions were problematic. As a result I came back to mild fin rot affecting all of the angels. Normally not a problem but now with no more access to antibiotics through pet shops it’s become more of a challenge.

Working through several options with no luck I eventually went with an extended 3 week treatment of melafix which seemed to do the trick. Fins are showing good recovery growth.

At the same time I’ve added Purigen to both filters - this is experimental. Over the past year, even when the tank was healthy, at any given time there’s always one or two fish that would have part of their pelvic fins missing. It seemed as if fins would get to a certain length and then melt away half way up the fin to a point where it would break off. As you can imagine this was frustrating. I suspect that even though I have been carrying out 30% water changes very regularly (2x per week) the water conditions might not have been optimal. Even with low stocking levels. So I am trying purigen to help lower ammonia levels even further.

So far I’ve been using purigen for 4 weeks and fins appear to be regenerating without sign of decay so early results look promising.

Purigen is a definite win. (This does not substitute for water changes but merely complements water changes). Fish are noticeably happier and lively. No more fin melt issues.

Wow nice fish. I found that when I was keeping altums API aquarium salt kept them alive. Especially when they were scratching themselves. I also rarely changed water but just did top ups. I have since changed to at least weekly 50%+ water changes. Great to see your still keeping them.
