Dovii growth underwhelming

  • We are currently upgrading MFK. thanks! -neo
I also agree with the water changes I rescued an Id shark he's in a 120 for the moment but he's grown about 9 to 10 inches since I got him. I do atleast 50% water changes a week

Agree with the others, with one additional caveat. Understand that large, massive water changes all in one shot, may not be safe with your tap water, and your fish. Lots of things need to be considered before one begins doing massive water changes.

In my tanks, with my fish, my biofiltration, my tank parameters, my tap water, and my water conditioner - I can personally get away with that, year round.
You on the other hand might not.

When it comes to water changes, one size does not fit all.

Aree with RD,
I find it easier to do a 30%-40% water change every other day than one large once per week.
And if your water heater doesn´t have capacity tomaintain stable temp, that can be problematic-
In winterr mylakeMichigan sourced water could dropinto the 40sF, a 40% water change was all mine could handle without dropping in winter.

But I also believe genetics are often blamed for shoddy fish keeping practices, such as wimpy water changes, and high nitrate (anything abovd 5ppm).
 
Update . Started 50%water changes every other day for the last month . Also have him in a 150 gallon by himself now . The water changes def improved his colors and he looks more robust but not much longer yet . We’ll see how the larger tank affects him now .
As I said earlier water changes with low nitrates are definitely a requirement but most importantly his diet is what’s going to yield the best results in combination with clean water.
 
He’s a picky eater . Currently his staple are bug bites and I give him a night crawler twice a week . Hes not into the hikari pellets for some reason or the freeze dried shrimp
 
Personally I would stop feeding night crawlers, at least until he is better trained to eating an assortment of dry foods.
FYI. Worms, like most fresh/frozen foods consist of approx 80% water, a non nutrient. So while they initially give the fish a feeling of being full, and are far more palatable to the fish, they are not a great choice for a picky eater, that apparently is not showing good growth.
