I have a Marineland Emperor 280 HOB filter on my 20 gallon tank, which has lots of cherry shrimp, 3 Bamboo shrimp, and 3 unknowns. Some of the cherries have eggs. I cut up a fish net and placed it over the filter intake of my Emperor 280 HOB filter. I was wondering if the holes are large enough for the RCS zoe or shrimplets to still get through it?

A block of sponge (like a sponge cartridge for an Aquaclear hob filter) would be better.

I would assume so, but I was wondering if the holes on the net is still too big.


BTW, I did buy one, but I noticed the gaps in the AC filter are very wide. I would not be surprised if the zoe or shrimplets would get trapped inside them.

I used one on a hob, no problems. The shrimp fed on the surface of the sponge.

One of my tiger shrimp babies (well she's all grown up now) is berried and the shrimplets are due to arrive in about 25 days. Some of my other females are developing saddles.

Would it be ok to put the expectant female in a breeder net (with java moss in it) within my tank a few days before she "gives birth"....then removing her but keeping her shrimplets in the net? The net is approximately 6-1/2” x 5” x 5-1/2” tall.

I tried using a prefilter but it slowed the flow down to the point my shrimp were climbing into the outlet tube and getting stuck. This tank is in the bedroom and hubby is refusing to let me set up an air powered sponge filter because of the noise.

That is one of the reasons I went to using my undergravel ssystem, and it works well for me.

As to the noise, the air pumps Ihave are even quieter than my HOB's. Have you tried setting the pump up on padding in a shoebox or something like that?

It all depends on how big the gaps are in the net and the pores are in the sponge! Not all nets are the same, it depends on the type of the net. You can usually judge if the gaps are too big by looking at them.

I can tell you about the AC sponge from my own experience, I had baby shrimp crawling in and out of it the entire time I had it on. The pores were so big I had a few babies that made it past the impeller and found them inside my filter. I would recomend using either a fine mess/filter bag or sponges with fine pores.

I agree with NeonShrimp.

It all depends on the type of net. A brineshrimp is probably fine meshed enough that a shrimplet couldn't get through, but I couldnt say for certain.

a swatch from a very sheer nylon stocking rubberbanded over the filter inlet. If that is still too 'porous' then you can fold it double and a shrimplet would have to be very tiny indeed to get through. It does work with very small anabantoid fry.

The disavantage of using a fine mesh cloth is that it will for sure clog easily. Regarding a stocking, I know it stretches, plus it's prone to rips and tears, so a bigger hole can easily be created.
