Hi bros!! Im from manila and i bought my first FH(the one who's not eating a week ago)about a week ago. I placed him(or her) in a 50 gal tank, he's about 2.5 and i start to notice a habbit that he's forming these days. He loves to put gravel in his mouth then blow it out in a different location. he does this on one spot of the tank until he see the undergarvel filter. So far i have four uneven spots in my gravel. all dug by him. Im worried that some of the gravel might enter his system. Is this normal for an FH? huh.gif

Hey bro ........

No worries ...... is very normal, flowerhorn
and most cichlids love to rearrange their tanks to some degree.
Flowerhorn being cichlids are territorial........ and digging is one way of establishing a territory.
Also digging (nest building) can be a response to reproductive urges.
This behavior maybe heightened in flowerhorn (beause they are hybrids)

Is your undergravel filter your only form of filtration?

If so please consider another type to replace your undergravel.
Undergravel filters provide biological filtration in the short term ...GENERALLY < this type of filter will work well (average mechanical filtration) up to a yr....at which point it will produce excess amounts of nitrates ... even with regular gravel vacuuming you will not be able to remove the amount of organic material that is collected. If you allow this your tank is primed for a chemical domino affect ....... to which your fish could suffer and possibly die<

A good choice that is fairly priced is the bio-wheel filter ..... is an excellent commercial filter. A great little device that provides all three types of filtration<( biological, chemical, and mechanical)
.......just my opinion *wink*

take care guys

yeah digging is very normal for large cichlids. It is possible some gravel could enter its system, but unless you have very large gravel rocks, it will pass through the system without any damage.
