As I have a fondness for bottom dwellers - in the aquarium that is, I look for types of food that sink as well as the traditional floating foods. This is meant to give the bottom feeders a fair shot at feeding time.
One of the foods I have tried was Tetra Tabimin. This is advertised as a complete food for bottom dwelling fish and claims to be biologically balanced for health colour and vitality. But on the same page that Tetra advertises this food as complete - it suggests feeding other foods for variety. I have to agree with the latter statement and would not use any single food without any additions for variety.
The advantage to this food is that it sinks, which is ideal for bottom feeders. Unfortunately this is the only advantage I can think of really, except that it is not messy to feed and does not stink as much as most fish foods.
The main disadvantage in my opinion is that most of my fish do not seem to like this and it just stays at the bottom until it dissolves and mucks up the water. Occasionally the plecto would eat a bit (and they usually eat anything) but as often as not it would just sit. You can actually see bits dissolving and clouding the water.
I have to admit being surprised at the ingredients list, which includes milk. I suppose fish will eat all sorts of things, but milk just seemed odd to me. I really can not say if this is why the fish did not eat it, but this is the only fish food I have bought that ended up in the bin. Uneaten food quickly dirties the water in a tank. I suppose if I were willing to with hold other foods long enough the fish would end up eating this, but I really do not see the point.
I found this a disappointing product from Tetra as I usually find their foods to be a very good quality. Maybe it is just my fish that do not like this, but with the variety of fish I have, I would have to think something would eat it. So for a fish food that my fish will not eat, and that quickly clouds the water, this product is only getting one star because dooyoo does not offer the option of no stars.
