Gel-based (or Live Or Frozen) Brineshrimp Or Daphnia - Experiences?

Has anyone tried/used this or the food in this range?  https://fishkeeper.co.uk/product/tetra-tetranatura-brine-shrimp-mix-80g

I used to feed my goldfish (RIP) frozen food now and again until he fell incredibly ill and had a near-death experience and which I could only put down to the frozen food, so I didn't ever want to risk that again with him. As a result of that, I've been very reticent about using live or frozen food with the tropicals - they get a mix of flakes and pellets plus a chopped pea once or twice weekly - although note from Seriously Fish that daphnia and brineshrimp are recommended for my fish (x-ray tetras and harlequin rasboras). I have tried some Tetra Delica sachets although stopped when the various problems started with the pygmy cories.

Thoughts on this or other forms of these foods (daphnia, brineshrimp) welcome, especially whether others have experienced problems. Thanks.

I have cories in my tank, so I feed frozen live daphnia every other day and sometimes frozen live bloodworm (though not as often because I don't like chopping it up!).
On a non-frozen day I put 3 different types of food in so that all fish are covered:
Hikari granules – for everyone
New life spectrum cichlid granules – just a few for my Bolivian Rams
JMC (I think!) – sinking meat-based pellets for my cories.

On alternate days I also put in some cucumber or courgette for my BN plec.

I know this seems like a lot, but the overall amount is not a lot, it's just made up of a few different types of food so that everyone is catered for.

I've had no fatalities in that tank for months now, so I do think everything's working out well and the live frozen doesn't seem to be causing any problems. Never tried the gel-based food though.

I've never had problems with frozen live food. With the goldfish, did you put the cube in the tank frozen or defrost it first? I have read of problems with fish eating a frozen chunk which is why I always defrost mine before putting it in the tank.

I have a quartet pack of frozen food - blocks of dahnia, brine shrimp, mysis and bloodworm - for the main tank and betta, and frozen cyclops for the 50 litre tank with its tiny occupants. I feed one of these on a Sunday. The only 'problem' I have is that the betta refuses to eat daphnia until he realises he won't get anything else 

The rest of the week they get a mixture of flake and pellets.


The only gel food I ever tried was Delica but it was too expensive to use on a regular basis so I just tried the one pack.

Many thanks, everyone - all very helpful indeed.

Re the problems with my goldfish, it was the quartet packs of frozen food which I used to feed him; I sliced off a quarter or a half of a cube, put the piece of cub in a mug and filled it with just enough boiling water to cover it, then swilled that until it defrosted completely, then filled the rest of the mug up with cold water, let it sit to cool, then poured it into the tank. He sat on the bottom for the best part of a week, sunken into the substrate without moving except for occasionally to lift himself up or tilt himself differently as he had a sore belly area, and was clearly very ill, then eventually did a very stringy white poo and eventually responded to Internal Bacteria Infection treatment or coincidentally recuperated around that time, and took another few days to eventually get back to normal.
